[Bug] Pathfinder loses support gems on refunding Concotion?

Hi y'all!

I'm playing a pathfinder right now and liking it, but i think i found something wrong / bug in the game.

While refunding my Concotion passive to try another element, i can't seem to find the support gems i had in it. Refunding back to what i was using didn't gave back my gems.

Is it a bug, or i'm just dumb and it went somewhere else?
