Auto Numbering Wizard Total Track Count

My second idea ... which track related tag-fields are stored within the mediafiles, ...
and do they contain the correct values, for example: TRACK and TOTALTRACKS ?
RESPONSE: When writing metadata for these files, all fields are ALWAYS blank to begin with - I tag freshly and cleanly from beginning to end.

Within Mp3tag a 'blank tag-field' does not exist. Do verify whether your track writing procedure has created the tag-fields TRACK and TOTALTRACKS within the m4a file.
If there is one m4a file, which does not contain the tag-field TOTALTRACKS, then try to find out how.
