Why have I not received the corresponding reward after completing the challenge?

After entering the game following the November 5th patch update, I noticed that three completed tasks did not grant the corresponding rewards, including the SCW-10 KTS100 and the KORD 6P67. I'm not sure how this bug was triggered.

I've tried numerous times using methods suggested by some community players, such as completing a match or restarting the game, but none of them worked. I hope this can be fixed.
