Maybe this link can help.
Battery 4: Preset Browser Inaccessible Due to Too Many Tags – Native Instruments (native-instruments.com)
Let me know how it went, good sir!
Where...?
I don't understand...
That link won't help you at all. It's about when you have too many tags listed, it will make the (non-resizable) Preset browser area invisible/inaccessible.
This is a shot in the dark, but... could you try re-setting the BATTERY 4 database?
(Make a backup of that Battery 4 folder if you want.)
