Windows Explorer and Mp3tag Comment field disagree

Would you not call that a bug?

No. Or if at all - then in Windows Explorer.
There is a peculiarity with the field COMMENT in the ID3 standard.
It allows to create such COMMENT plus extra name field and still treat them as COMMENT field.
e.g. iTunes used them for COMMENT ITUNNORM.

Unknown field "COMMENT NONE"

Hello guys! I've come up with an mp3 file that has a tag field called "COMMENT NONE", which is different from the field "COMMENT", and which doesn't show up as a normal tag. The only way I'm able to get to it is by going to extended tag properties. But even there, if I want to create that field, the list of available ones only shows "COMMENT", which is different. I would like to use the values in these fields as I would any other one. Is there something wrong with the tag itself? Thank you in…

So there is still no bug.
I would find it much more interesting who (or which program) created those extra comment fields that puzzle you. i would remove them if there is no real need for the fields.

As you noticed: MP3tag shows (contrary to the Windows Explorer) all comment fields. It is the non-tagging program Windows Explorer that causes your problems.
You have now all the tools at hand: you know that there may be more than just plain COMMENT fields, you know (now) the extended tags dialogue, you can pinpoint which fields you want to treat - everything much better than that what the Windows explorer offers you.
