Can't uninstall korg plugins mac

[Kaneda]

I installed the Korg Collection 2 plugins for mac, but decided not to buy them.
I have completely removed everything from Korg on my mac (library, preferences, you name it, it's gone), except for the Kross 2 plugin, then rebooted.

For some reason, the plugins still show in Ableton's plugin list, even after a rescan. I have checked every, and I mean every, folder on my Mac, there's absolutely no sign anymore of those plugins. They don't only show up in Ableton, they actually still work. But I've erased them...

Has anyone had this problem before ?
