I have a weird bug where some tracks numbered 2-9 won't open in MP3Tag. This occurs whether I open the directory through mp3tag or through the explorer context menu or drag all the files into the mp3tag window. The weird thing is that if I change the track number for the tracks that don't open to something above 10, then mp3tag will open them and let me edit everything. This doesn't happen all the time either, just on random albums here and there. I checked if there are APE tags in the files and there aren't, I also unchecked reading of APE tags in the mpeg options, that didn't help resolve the problem either.
EDIT: Actually, the files won't open if I change the track number to anything other than in the 1,10-19 range for the albums that don't work
EDIT 2: It appears that renumbering to that range doesn't always work either
