Challenges completed, unlocks not rewarded

After the challenge update I have several challenges that are completed but I haven’t received the weapons they unlock.
Yes, I’ve checked that all the requirements were met. Yes, I’ve restarted the game multiple times. Yes, I’ve played multiple matches from start to finish. Yes, I’ve cleared the cache. Yes, I’ve power cycled the Xbox. 
I’ve completed challenges after the broken ones and have gotten unlocks past them like in Danger close. I have both 1 & 2 done but it only unlocked the SG 553 not the QBZ.
