Hi.
Tags with comments are not saving; (does anyone have any solution to this problem?
You can see my problem in this video: https://youtu.be/oQK4b1I4jno
the language token for tag fields has to be the same as the one used by Windows.
You can set the tag language token in
File>Options>Tags>Enhanced
Based on the video you've posted it's most likely pol that's working for you.
yesterday i spent 4 hours trying to fix this problem and nothing 
yes I tried to add the "pol" token and it did not help either
this is how it looks like in the mp3tag: https://youtu.be/XN5fMc5KCNA
Do you have APE tags in the file?
And what are the settings in File>OptionsTags>Mpeg?
Uh, in the old days it sometimes worked to let mp3val do its job.
The settings look principally OK to me.
Which leaves the question about the APE tags.
(and perhaps really a check whether the file is OK - see here for some links to utility programs).
How can I check if I have APE tags in a file?
By default there should be a column fairly far to the right that shows the tags in a file.
Alternatively, select the test file and open the extended tags dialogue (Alt-T) - there the dialogue title shows the found tags.
Okay. Problem solved. I have to use "Tools> Options> Tags> Enhanced" PLK here, not POL ...
Once again, many thanks, gentlemen, for your interest. Special thanks to @LyricsLover !!
Solution: Check carefully in "PowerShell" there is a correct abbreviation for your language:
