Compilations don't show up under "Appearances" of a track?

If you click on any track, you'll see the coupling collection doesn't come up under appearances.

Mostly fixed, but Egao ni Namida (Gaki Cover) still isn't showing up as having appeared on Coupling Collection 2...

maybe because it's a cover + a compilation appearance?
