The image should speak for itself!
I get this with:
Monster MIDI Pack 1 (but not 2)
Monster MIDI Fills Pack 1, 2
Library of the extreme 1, 2, 3
Songwriters pack 1
"Family" column showing default folder names instead of actual family names, and MIDI file names not having whitespace, instead underline is shown (which EZD2 doesn't do).
I have tried Restore MIDI Database, doesn't help.
