Entity Framework - fields are missing in the table in my Data Model

I'm relatively new to this stuff.

I created a .Net Entity Data Model,开发者_StackOverflow中文版 but three fields are missing in one of the tables. I tried creating a new one from scratch, etc.

I can see those fields in the Model Browser(when I expand Tables/Views => tablename), but not in the DataModel.edmx itself.

I'm using SQL DB.

Why can this be happening? Any help greatly appreciated.

It would be helpful to know the types of the fields that are missing. In any case, I have see situations where I had to drop the table, update the model, then re-add the table and update again. The EF 1.0 designer is a little buggy.
