Without seeing code it's difficult to tell where the problem is.

First delete the third table from the edmx file. Now add a new unique/identity column to the table 3 in database to make it appear in the model/edmx. Set proper relations on table 1,2 and 3. Now update the edmx file from the changes made in DB.
