Not inserting lyrics tag?

[skrivskithar]

Hello, first time trying this app. My intention is to get tags from Musixmatch. I was succesful in getting .lrc files, however the program is not entering the tags in the files (with the lrc file checked off). What am I doing wrong? There are no error/failed messages

Only MP3 supports synchronized lyrics, other formats need unsynchronized lyrics.
If that's not the issue; could you please provide which format you use and example track name, so we can test? Thank you.
