Table not mapped to Entity Framework data model

Table not mapped to Entity Framework data model

Hi, I came back with another question, I started using EF and I have problems with it.

OverView:
I made an EF model and found out that one table (named UserRoles) did not appear in the EF model diagram, I tried to add it through the "Update Data Model", but the wizard did not show me that the table adds (as if it were already added), I also tried to update the model using the "Update Data Model" wizard, this did not help.

Explanation of the problem:
Original DB diagram.
