Why does my Database (null) return null when I search for id?

I save in my bank using sugar every time I get a new notification, it works correctly, then in a fragment I populate a recycleview with all the database notifications, it also works correctly, but now when I try to delete from the database by id I can not, my database returns null for some ids (see the debug image), I have tried to understand but I can not understand why.

Bank addition code:

public void onMessageReceived(RemoteMessage remoteMessage) {
        SugarContext.init( this );
        Log.d("igr", "Mensagem Recebida");
        if (remoteMessage.getData().size() > 0) {
            Log.d("igr", "Message data payload: " + remoteMessage.getData());
            String titulo = remoteMessage.getData().get("title");
            String mensagem = remoteMessage.getData().get("text");

            try{
                Notificacao notificacao= new Notificacao(titulo,mensagem);
                SugarRecord.save(notificacao);
                SugarContext.terminate();
            }catch (Exception e){
                Log.d("igr", "Erro ao salvar notificacao no DB: " + e);
                SugarContext.terminate();
            }

My template:

package br.com.igoroliv.youtubecanal.DataBase;

import com.orm.dsl.Table;

/**
 * Created by igord on 03/07/2017.
 */

@Table
public class Notificacao {

    private Long id;
    private String titulo;
    private String texto;


    public Notificacao(){

    }

    public Notificacao(String titulo, String texto) {
        this.titulo = titulo;
        this.texto = texto;
    }

    /* gets e sets */

    public Long getId() {
        return id;
    }

    public String getTitulo() {
        return titulo;
    }

    public String getTexto() {
        return texto;
    }
}
