I have some MP3 files which are reported by MP3Val to have multiple APEv2 tags in each file. I'm trying to use MP3Tag to remove them, but getting nowhere.
I have gone into Mp3tag Options and checked all options for both "Read" and "Remove." (I don't care if it also removes the ID3 tags, since I'll be overwriting them from a text file anyway.) I've also tried it with all "Read" selected and only APE selected for "Remove." With the files selected, I've tried both Ctrl-x and the button up by the Edit menu. No matter what, the tags still seem to be there.
It could be that if you have several layers of APE tags that you have to repeat reading and deleting several times until the stack of APE tags has been removed.
I think that MP3val reports APE tags as "Garbage at end" - so perhaps several rounds with MP3val may also help.
I would try the following settings:
ON to read and delete APE tags .
OFF read, write and delete for all other tag versions.
Re-read the files with these settings,
select "Delete tag" - and watch the column that shows which tag versions are in the file(s).
