Mp3tag doesn't recognize a few tracks

[ohrenkino]

What does the status bar show: how many files have been loaded?
And if all this does not lead anywhere:
could you supply a working and an ignored file?

Some MP4 files are not listed when starting from context menu

I have ensured that the download executed properly, restarted my PC, and everything else looks fine but if I right-click on an mp3 and select MP3 Tag, it brings up the screen but with no file selected. If I change directories to see files, it only shows those files that already have MP3 Tags.
