Missing tag information in mp3 and mp4 files in Windows Explorer

I found e.g. this thread with the search words "mp4 publisher"

Publisher tag not embedded properly

Hi. I'm editing tags for my audiobooks (.m4b) and everything works flawlessly except for the Publisher tag. I added a new column and choose field & value %publisher% for it (the %publisher% field is an already available extended field in Mp3tag). I added the values for my audiobooks and hit Save. When I right click on the file and hit Properties, as well as when I load my audiobooks into an audiobook player, the Publisher field is empty. I check the file with MediaInfo, the tag is registered…

I doubt that the windows explorer is a vlid testbench to check whether information is available in tags.

If you want to see where the data is in MP3tag, see the extended tags dialogue Alt-T
