title: Tables don't show when re-adding them to entity-model (edmx)
body: <p>I have a db with 5 tables. At the beginning, I've added those tables in, but then decided to remove some due to some relationship compile error.</p>
  
  <p>Now, when i want to add them back, i'm opening the edmx file -> update model from database... I don't see those tables under add tab, but only under the "refresh" tab.</p>
  
  <p>How can i add them back?</p>
