Duplicate ID3v2 tags

I use foo_discogs exclusively to tag my files. None of them are hand-tagged in any way or changed by any program other than foobar2000.

I was reading about a problem with foo_dop and album artwork, and the problem was caused by duplicate ID3v2 tags in a file. A long time ago, I had noticed that some of the tags that I had written with foo_discogs were disappearing. I re-tag when I notice it, but sometimes it doesn't work. It happens on seemingly random tracks (not all the tracks on any particular album, for example).

I cracked open the files in a hex editor, and sure enough, there were duplicate ID3v2 tags. I opened foobar, found the files in my library, and using MP3 Tag Types... from the context menu, I unselected ID3v2. Voila! The tags returned to normal. As you might expect, going back into MP3 Tag Types... showed that the ID3v2 box had "magically" re-checked itself.

Does anyone know how I can remove all the duplicate tags without losing data and without killing my harddrive by reading/writing 10,000 files?

hm. serious thing... ill try to check it on my mp3s.

ive checked first file, wich i have tagged yesterday... in foobar 0.9.5  and foo_discogs 1.2
no duplicates were found...

what you have here:
Preferences->Advanced->Tagging->MP3->Force Preferred tag writing scheme on all files regardless of existing tags

in my case it is checked...

i think that it is not foo_discogs fault any case... because, as i suppose, foo_discogs using standart foobar2000's  tagging mechanism...

Well, assuming that it was/is a bug, can anyone write something that scans files for duplicate tags and removes one of them? I do know PHP and I'd throw something together with that, but I have no experience working with binary files or ID3 tags.

Very weird problem. foo_discogs use standard foobar APIs for tagging, the same ones used by the properties window. What is the tag duplicated ? is it always the same tag ? On files that have duplicated tag do you see the dplication in the properties window ?
Did you use another app that may have rewritten some tags as ID3V2.3 ? Foobar writes ID3V2.4 and I lost some tags using a DJ app writing ID3V2.3 tags...

My brother used WMP11 in my computer, and all " %genre% " tags, i.e. " Pop ", were replaced with " Other " .
