I get a lot of warnings of the form

Warning: ID3v2 TCON frame has non-numeric genre index 03.07 at offset 20377 in file........

This only appeared when I made another change

All my GENRE tags are of such a form from MUSICHI. Why is there a problem in the MP3 files with the TCON tag

This means the TCON frame in these files is formatted incorrectly. What was the "other change" that caused these messages to appear?
