Media Rack 9.5 - Am I missing something?

So my issue is the same, however I was able to use the tip above to show the folders in the top box. However, I can only see MIDI files and not the wav or audio files. I’ve tried every setting I can think of for “ALL FILES” but it still only shows MIDI files. If I go back to the HOME screen and select Show All Items and All Media Types, I now see the wav/audio files fine and they audition fine… but they don’t show in any folders.
I need to use the folders I’ve set up for the audio files… why can’t I see them when I’m in the file browser?
