You can only use Find *Album* Info (not Find Track Info!) for tracks ripped
from a "mix" CD if at the very end of the Find Album Info process you press
EDIT and then select "This is from a custom mix CD" - otherwise you will
indeed see the behavior you're describing, as the tool is meant to apply to
albums, not just single tracks.
It's possible that that checkbox may still not be what you want, in which
case you will indeed simply need to use Advanced Tag Editor or edit the
tracks in the library directly without using Find *Album* Info. =\
