challenge "iridescent hero" not working

saturan

Hello,

I'm trying to do the challenge "iridescent hero" from tome 2.

I'm supposed to get two iridescent emblems as a survivor in one game.

I've managed it, but the challenge hasn't been validated:

Or does the challenge require me to get exactly 2 iridescent emblems? And getting 3 of them doesn't validate the challenge?
