Batch Converter losing track numbering

[Floyd]

I use mp3tag to edit the metadata on my music.
I have copies of my music in
FLAC Uncompressed
FLAC level 5
ALAC
LAME
I like to have my track number like 01/15 and discnumbering 1/1 or 1/2 etc.
I usually make changes the the FLAC Uncompressed file then use Batch Converter to make a copy in the other 3.
The issue I find is that for the conversion to FLAC Level 5 it always does not pass the track numbering over and
its reverts to 1/15. that is not the way it was and I have to renumber it again.
The ALAC doesn't care about track numbers with double digits.
The LAME conversion works out ok.
Is there something I'm doing wrong or ?
Its been this way for as long as I can remember.
Thanks
Floyd

It sounds like the issue is with how the FLAC encoder handles metadata during conversion, some versions strip the “xx/yy” style track numbers. A quick fix is to check your Batch Converter settings or run Mp3tag after conversion to auto-renumber so it stays consistent.
