Media Bay search not finding things that are indexed

Hi there,

The Media Bay search is acting very weird (gif attached).
I have a bunch of track presets where the names are in the form “LASS - [section]”.
If I search for “LASS” it doesn’t find any of them.
Whereas, if I search for say “Violin” it finds them.

I don’t think it’s because of the Category attribute either.
A similar search for “SJBP” matches all the presets with that in the name no problem (second gif)

Any ideas if something is messed up, or if this is just how it is?
I’m on 11.0.10 Build 321.

Thanks!
