Entity Framework 6 and Oracle 10g: Tables are imported, but entities are not created / updated

Question

I moved my database from local development (Oracle 11) to the development server (10g). Then I tried to update my EF6 model (DB first), as 2 rows were added (regular number(1,0)rows). Having opened the model’s browser, I see updates in the table, but the entity is not updated accordingly. Retrieving the entire table and re-importing it, or creating a new model and re-importing the entire database gives the same result. I am using VS2012, EF6, Oracle ODP.Net in my latest version (12.1.0.2.1). Any ideas? Do I need additional privileges? Is there a way to get "verbose" output from the generation of the script model? Any ideas and help are appreciated! thank you

Edit: Let me add that creating a property manually and then displaying it works.
