Tracks with NO composition

so, i ask again to the @support a solution for this topic. i summarize the problem:
-many albums (identified) with tracks without a corresponding composition
-this happens even when the track file has a COMPOSER TAG.

as far as i have discovered in the forum, this is not a normal behavior: every track has an associated composition, that can be a rovi metadata composition, or a local library composition if it’s missing in rovi.
see for example:

i don’t know if the problem can be caused by some library settings, or what else.
i think i have already asked a support for this… i’d like an answer.
