Thanks for your reply @vova
I have already checked this, sorry I didn’t mention that earlier.
In the tags of the files this is not the case; I have only put in basic tag information and the title tag only specifies the title of the song (so no prefix, like “Solaris, film score” or something like that).
In Roon however, this is identified in the way you specify (so title tag is: “Solaris, film score: track title”). I have already tried to change this in Roon as well as directly edit as well as per the option “prefer file tag”. Both have no impact unfortunately. It keeps seeing the tracks as one continuous track.
