Danger Close 1 Challenge Complete but QBZ still not unlocked

So I started playing BF6 right before the change in the challenges to make them easier. When that happened, I was half-way through the challenge. Now with the change, it has the challenge done in the challenge tracker but yet I have not unlocked the QBZ-192... I have tried completing multiple matches, hard reset my console to clear the cache and hoping that it would fix the problem but nothing has happened. Anything else that could be done to unlock this?
