Seasonal challenge is put as tracked while it shouldn't be able to mark it
So today when I logged in, I noticed I had a seasonal challenge marked called "Haunting Cacophony". When I went to unmark that challenge, I noticed I wasn't able to find it.
Further browsing through Bray.tech, showed me that it seemed to be a challenge for week 10.
IS there a way I can unmark this one? It sucks losing out on one marked challenge due to this :/
