I can't seem to replicate this -- I've tried both methods : Clicking on 'Test List' here:

And going to the bottom menu and choosing 'Remove from Test List'

Secondly I tried clicking the red minus mark here

And neither method appears to delete the fragrance in the owned section.
So I can't seem to replicate this -- are you still having problems with it?
