Using mp3tagv2.73 with Windows 7 sp1 Home premium. When I edit a ID3.2 tag in Audacity and then view the tag with Mp3Tag, some of the fields (perhaps only the numeric ones like "Year", e.g.; 2015 show up as 2015\\2015. When I reopen the file in Audacity and other editors it displays correctly.
Have a look at these files in Mp3Tags extended tag-view. (ALT-t)
You probably have 2 year-tags.
You can solve this with an action "Remove duplicate fields".
The same happens while tagging with MediaMonkey.
[X] seltsame Anzeige im Jahr-Tag
Is there a way to prevent this from happening? It is a constant issue here and it takes a while to clean up 20K+ files.
Thanks...
Do you refer to MediaMonkey?
Just look for MediaMonkey.ini and add the following lines to the ini-file:
[MP3Tagging]
DisableFrames=TDRC;TDOR;
EnableFrames=TYER;TDAT;TORY;
Yes I found that looking at a German Language post on this site. Thank god for Google translate 
many members of my extended family in Europe speak German (Swiss) but not I.
BTW, less than an hour to get a response. I like this forum!
Thank you for confirming what I subsequently found. Merry Christmas/Happy Holidays...
