Progression not working properly for weapons and vehicles (Solo/Coop AI)

same here , i have the average of 40 kills per match with bots at any difficulty or without them just players , any killing neither bots nor players doesn't give me any progression not even a single kill count for any of my weapons all the numbers stuck i mean my G57 is stuck at the number of 46 kills this exactly happened after the first time servers were relaunched because of xp farmers before that this was normal and i could unlock new weapon attachments
