Tracks with NO composition

i was loiking for one example, and returning to one of the “fails” i have found out… that it worked.
maybe the problem is that i first changed the setting to “prefer file” in the multi-part section and AFTER i have populated the WORK tag (and rescan).
but it seems that the setting change takes affect only if there is a WORK tag… otherwise it reverts to “prefer Roon” (roon is the only program i know when you cannot see the apply setting, you can change the settings, but not see them!!!).

so i’ll look more deeply in other files and see if i can make this cabalistic recipe work.

i have found in the past another situation where the multi-part setting is affecting the composition credits… so i really guess that this is the final solution:

so, @Tony_Casey, i really thank you for your help.

i repeat myself here: i’d like to have a comment from someone of the @support team
