There are a few hundred MIDI styles that intentionally are not shown in the StylePicker. This is because they are part of Multistyles (a style that has 12 substyles for example gets 6 styles made for it, but only the first one -named Mystyle+.sty would be the one to play).

I'll update the "total styles" found so that it doesn't count these styles, and then the totals will match up.

So, in summary, it doesn't look like you're missing any styles. You should press Other - and show styles that are N/A and then list only styles that are not found, to see if you are missing any.

Have Fun!
