Duplicate Bunny Spiral Catalyst

[J4nuz]

I cant for the life of me figure out what to do with duplicate items needed to craft descendants. More specific I did the early quests that unlock all 4 of the materials for bunny and crafted her.
Next day I re-did some of those missions with a friend and I got a second catalyst that I dont think I have any use for except occupying slots. Cant seem to be able to dismantle it or trash it and I doubt it's even possible to re-craft bunny a second time for whatever purpose.
Thoughts?

It is to craft her if you decide to kick her off your team.

Had no idea that was even an option but now I see it in the descendant list
