Sorry for the delay. Yesterday I was occupied by deleting Kodi from my machine, buying an XBox and installing XBMC 3.0 Nevertheless it didn't work too.

Can you post a screenshot of the tags for one of the song files, using the extended tag view (ctrl-t) of Mp3Tag

Hmm, I've never heard of MP3Tag. But if exiftool is also ok?

Code:

while read line; do exiftool "$line"; echo "----------------"; done < <(ls CD*/*.flac) >> ~/tags.txt

For checking and modifying the tags, I'm using Easytag for ages. It's the first time I run into trouble.

Also the full debug log will help.

Is this the album? https://musicbrainz.org/release/6e929e98...a437af5b2a

Yes, it is.

The debug log complains:

But there is a tag. The only thing I can imagine is the usage of special characters like the ™ in the comment field.
  
To get sure, I've restored the original directory structure with the subfolders named CD1..3
