Recently Media Bay and all its variants stopped showing any filter values - see attached.
The filter types (Category, Style, Character, etc.) are all available, but nothing is listed under them. If I select an item in the Results section and use the Attribute Inspector I can see the various filters and what they are set to. As far as I can tell no content seems to be missing.
When I start in Safe Mode and use the default Preferences it has the same problem.
This is all in 10.5.20.
I also opened 10.0.40 and initially it looked like normal with all the Filter lists intact. But then I hit the Reset Filters button and it all disappeared so it now looks like 10.5.20.
