Maximum 255 tracks?

[brainwash]

Hi, my first post here.
I am converting a 500 track compilation from FLAC to Apple MPEG-4 Audio and everything works great until it gets to track 255. Once it hits track 255 the numbering starts over, even though the original FLAC files are numbered 1-500. So what I'm getting as the final output is Track 01, 01, 02, 02, 03, 03..etc; when it should be 01, 02, 03 04, 05...etc to 500.
I can't figure out to convert the remain tracks in order. I've tried converting tracks 256-500 in a separate folder but it still starts at track 01. Any help would be greatly appreciated! - cheers

Figured out that the numbering was messed up on the source files. All good now...
