Track numbers from mp3 don't get imported

Some of my tracks don't get imported with the correct track number. They all show the same track-number (normally the "1", but I also saw the "4", so I guess it's a bit random?).

This is an example album were it doesn't work: https://musicbrainz.org/release/beb47345-3c11-428a-beb9-246e793a9750

I think it is related to mp3-files. The affected files I saw all were mp3s and the files were everything was fine were .ogg.
