Convert file name to tag does not work

Hello! I use version 3.27a. Earlier everything worked well. But now the converter does not do what I expect. For example: There is a file with the following name "Behind the Gardens, Behind the Wall, Under the Tree... (feat. Walter Keiser, Pedro Haldemann) (320 kbps).mp3".I use the convert string "%artist% - %album% - %track% - %title%" after I marked this track. But the software refuses the conversion. The "OK" Button is greyed. Can anyone tell me what I am doing wrong? Thanks in advance. You can write in German. Joachim

The pattern that you gave in the convert string does not match at all the file name.
The file name does not have any hyphens as far as I can see.
ALso, TBH, I see only the TITLE and the bitrate (which cannot be set).
A screendump would help.
You could try as
Convert String: %title% (%dummy%)
