Weapons not unlocking

I have exactly the same issue; it's incredibly annoying.

My Rapid Fire 1 challenge automatically completed when EA released the patch which lowered the challenge completion requirements.  However, I haven't received the Kord.  My current challenge wants me to use the Kord to progress, but I can't because it's locked!  I have the same issue with the Assault spawn beacon.  So in other words, my Assault class progression is completely bricked....

I have reinstalled the multiplayer, updated to the new patch today and played quite a few matches today, and the locked weapons/items are still locked.

Please fix this!

I'm experiencing the same issue.
The Assault class challenge is particularly problematic,
as the beacon remains locked, preventing me from progressing to the next challenge.
I've tried reinstalling the game and various other solutions,
and even after today's patch, I've attempted numerous fixes,
but the problem remains unresolved.

My situation is the same. Even though I completed Challenge Assault 1 and Challenge Support 1 the rewards did not unlock.

Had the same issue for the past couple of days. No fix helped. PC STEAM

After the lowered requirements have taken effect I still am unable to use the base version of the NVO-22BE, SCW-10, and my deploy beacon, I have completed and can use both the SMG and Assault rifles after those unlocks. and cannot continue progressing my assault challenges because the deploy beacon is complete but not unlocked. I have restarted my computer approximately 7 times since the update and finished approximately 20 normal multiplayer games completely through to no avail. I'm starting to get frustrated that this is a problem because I would like to be able to remove attachments from the versions I do have unlocked from the battlepass and weapon xp progression earned via RedSec. Here are the screenshots to show my frustration after completing yet another game to attempt unlocking the weapons.

I'm locked out of using 2 of the best weapons in the game because of this issue and I'm getting very sick of it. You're not alone and I hope they find a fix for this soon. 

Same problem for me plasplasmeding. So until they fix it I don't think I will be using Assault class

Same problem

Try'd to do it again but its still not unlocked. 
Only thing missing is Re-insatall the game. but i dont see how that will fix it tbh. 

Same issue across all classes: KORD 6P67, QBZ-192, SL9, KTS100 MK8. Challenges are marked as completed, but no unlocks for a week.

Same issue with the redeploy beacon and psr. Dont know for what else yet. Thought they would have fixed it with this patch.
