SOLVED: I can't add movies to existing collections (empty list)

[TheDreadPirate]

Ok.  Open your dev console again and repeat the process of adding a movie.  But you only need to open the prompt to add a movie to a collection.  In the dev console I want you to click the line that pops up right when you open the prompt.

   

The one that contains "IncludeItemTypes=BoxSet".  It will move you over to the Sources tab and display the contents of what should be in your collection drop down.

   

What do you see?
