I don’t think this question of what constitutes a composition has ever been answered. There are posts going back years.
One thing I have noticed is that there is some kind of connection with multi-part composition grouping. If you go to “edit album” (for any album) and scroll to the bottom you will see the number of tracks vs. the number of recordings. Regardless of the spelling of the track title or the composers, only those tracks that are also “recordings” can be “compositions”. I do not know what this means.
So for example with my copy of Matt Brewer’s “Unspoken” roon finds 9 tracks and 2 recordings and only 2 of the tracks are defined as compositions.
