BF6 support assignment bugged out real bad

Is anyone else having issues with the support assignment where you have to use the airburst grenade launcher to deal damage? For some reason it only tracks, at most, 20 damage. So the initial explosion. On top of that, it will only track 20 damage per life with the grenade launcher, and will only track in lobbies with real people. So it won't track anything in casual breakthrough, only in conquest and escalation. I've had this bug and so has all of my friends. This is extremely frustrating. It is taking several days and unknown amount of hours just to get to 500 damage. This is really making us mad. Not sure what to do here.
