return inside the control does not send to the right maproute

Good afternoon, I'm trying to use maproute to control editing and insertion of data in the table, currently my routeConfig looks like this:

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        /*Sub Categoria*/
        routes.MapRouteWithName(
             name: "Editar Subcategoria", // Route name
             url: "CanaisDigitais/Subcategoria/Edit/{id}/{idp}",
             defaults: new { controller = "CanaisDigitais", action = "EditSub", id = UrlParameter.Optional, idp = UrlParameter.Optional }
         );
        routes.MapRouteWithName(
              name: "Deletar Subcategoria", // Route name
              url: "CanaisDigitais/Subcategoria/Delete/{id}/{idp}",
              defaults: new { controller = "CanaisDigitais", action = "DeleteSub", id = UrlParameter.Optional, idp = UrlParameter.Optional }
          );
        routes.MapRouteWithName(
            name: "Subcategoria", // Route name
            url: "CanaisDigitais/Subcategoria/{id}",
            defaults: new { controller = "CanaisDigitais", action = "Subcategorias", id = UrlParameter.Optional }
        );

        /********************************************************************************************************/
        /*Conteudo*/
        routes.MapRoute(
            name: "Conteudo", // Route name
            url: "CanaisDigitais/Subcategoria/Conteudo/{id}",
            defaults: new { controller = "CanaisDigitais", action = "Conteudo", id = UrlParameter.Optional }
        );
        routes.MapRoute(
             name: "Editar Conteudo", // Route name
             url: "CanaisDigitais/Subcategoria/Conteudo/Edit/{id}/{idp}",
             defaults: new { controller = "CanaisDigitais", action = "EditCont", id = UrlParameter.Optional, idp = UrlParameter.Optional }
         );
        routes.MapRoute(
              name: "Deletar Conteudo", // Route name
              url: "CanaisDigitais/Subcategoria/Conteudo/Delete/{id}/{idp}",
              defaults: new { controller = "CanaisDigitais", action = "DeleteCont", id = UrlParameter.Optional, idp = UrlParameter.Optional }
          );
        /********************************************************************************************************************/
        /*Rotiamento do fórum*/
        routes.MapRoute(
            name: "Topico", // Route name
            url: "Forum/Topicos/{id}",
            defaults: new { controller = "Forum", action = "IndexTopicos", id = UrlParameter.Optional }
        );
        routes.MapRoute(
            name: "Editar Topico", // Route name
            url: "Forum/Topicos/Edit/{id}/{idp}",
            defaults: new { controller = "Forum", action = "EditTopicos", id = UrlParameter.Optional, idp = UrlParameter.Optional }
        );
        routes.MapRoute(
            name: "Deletar Topico", // Route name
            url: "Forum/Topicos/Delete/{id}/{idp}",
            defaults: new { controller = "Forum", action = "DeleteTopicos", id = UrlParameter.Optional, idp = UrlParameter.Optional }
        );
        /*********************************************************************************************************/
        routes.MapRoute(
            name: "Posts", // Route name
            url: "Forum/Topicos/Posts/{id}",
            defaults: new { controller = "Forum", action = "IndexPosts", id = UrlParameter.Optional }
        );
        routes.MapRoute(
            name: "Editar Posts", // Route name
            url: "Forum/Topicos/Posts/Edit/{id}/{idp}",
            defaults: new { controller = "Forum", action = "EditPosts", id = UrlParameter.Optional, idp = UrlParameter.Optional }
        );
        routes.MapRoute(
            name: "Deletar Posts", // Route name
            url: "Forum/Topicos/Posts/Delete/{id}/{idp}",
            defaults: new { controller = "Forum", action = "DeletePosts", id = UrlParameter.Optional, idp = UrlParameter.Optional }
        );
        /*********************************************************************************************************/
        /*
         * Roteamento dos tipos da a genda
         */
        routes.MapRoute(
           name: "Agenda tipos", // Route name
           url: "Agenda/Tipos/{id}",
           defaults: new { controller = "Agenda", action = "IndexTipos", id = UrlParameter.Optional }
       );
        routes.MapRoute(
            name: "Editar Agenda tipos", // Route name
            url: "Agenda/Tipos/Edit/{id}",
            defaults: new { controller = "Agenda", action = "EditTipos", id = UrlParameter.Optional }
        );
        routes.MapRoute(
            name: "Deletar agenda tipos", // Route name
            url: "Agenda/Tipos/Delete/{id}",
            defaults: new { controller = "Agenda", action = "DeleteTipos", id = UrlParameter.Optional }
        );
        /*******************************************************************************************************/
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );

    }

But when I access the link and edit some value that gives an invalid state in the template and returns to the view it directs me to the url link

This is the code I use in the controlle to return when the template is invalid:

return View("Subcategoria/Edit", Modelo)

Could any good soul point me where I'm wrong? Note: Use MVC 4 and dotnet 4.0 can not update either.
