MCC Challenges Glitching

Hey so I would be playing the Master Chief Collection like I do. I am trying to do the weekly challenges but some of the challenges dont keep count sometimes. Like i would get double kills and spree medals and it wouldnt get counted at all. Anyone else with this problem?

I’ve been having the same problem with the Objective challenge. Been getting Odd ball kills, killing the flag and bomb carrier but still nothing. Can’t really expect it to be perfect right off the bat though. I’m sure it’ll get fixed soon.
