Small issue with loading Presets, showing ALL categories

Hi,
I noticed that when I go to load presets from a Instrument’s Load Preset dialog, the shown categories can get messed up and show ALL the categories.

When I have a instrument with many presets categories, I can select a category and then select a preset.
Then when I reopen the Load Preset dialog it shows ALL the categories, not just the ones that exist/are valid choices.

I also notice the same issue with NO categories selected, and no other filters, but I still needed to press the ‘clear all filters’ button (the button to the right of the ‘attributes’ button.

thanks
