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

@GRUExylo for every unused weapon/vehicle i also unlock like the first two attachments when i play with it, but after that i can make like 150(till indef.)kills n no further things are unlocked, n when i check the kill count on the weapon itself(like x/30 kills for example) its mostly 0 n sometimes some number but still below 10 even thou, like mentioned earlier, i should have like 110-150 kills with it. I played one time in normal multiplayer till i died first time n checked my kills on the weapon... those kills counted. Only the solo/co-op thing doesn't add to those unlockables.
