Real-type fields on the bank with loading problems Model

Some 3 or 4 months ago I had this same problem, that after I remapped all my Model, it solved. And now it's back to the same problem. It used to be float and now it's Real . In my Model is decimal and gives the error. I have already changed to Single, Decimal, decimal, float, double and continue. I use Sql Server 2012.

  

The 'CustoDiario' property on 'Liberation' could not be set to   'System.Single' value. You must set this property to a non-null value   of type 'System.Decimal'.
