Schema intellisense completion in SQL Server

I figured out today how to go to File | Settings | Editor | General | Code Completion and turn on the setting to always included Schema name in code completion.

Brilliant!

And then it stopped working, and for the life of me, I can't get it to work again.  When I start typing, I can see the table name, and the pop-up shows the schema, so DG is clearly aware of the table, but when I press tab, it doesn't include the schema name anymore.

Here's How I broke it:
I selected my database in the Database Explorer

I pressed alt+insert (windows)

I selected SQL script (I'm trying to use DG to write a sproc, which is another ticket)

When I got the new file, the schema completion just stoppped working.  Further, when I switch to my other consoles, where the schema completion was working before, it has stopped working.

I tried restarting DG, but no dice.

Any clues?
