Media Bay adding attributes?

I have my own with libraries, and I would like to quickly add attributes to them FX / Boom / Rise …etc
It’s really easy to click on the rating and add a star, but I can’t simply click in the sub category / sub Style or Category.

am I missing something simple?

thx

OK I found a really helpful post - Make better use of user Media Bay Categories - Custom Categories, here is how

It seems to be a pref setting so you cannot edit categories . Change the preference for an hour edit done !

I may not be understanding - after changing Prefs I still can’t seem to edit Categories or Sub Categories.
