Final "Support Specialist" challenge is incompleteable

Glad I'm not the only one dealing with this 

I do not get any progression at all. direct hit or near the enemy. I am getting the kills but it does not count. I hope they fix this soon.

It's bad enough that damage isn't tracking properly, if at all... 

... but now there is a supply bag bug that prohibits you from getting any more airburst nades. I throw a fresh bag on the ground, and it fills about 1/4 of the bar to get another round of ammo, and just freezes. So I wait, and throw another bag on the ground, it fills about 1/3 more... then freezes. Sometimes it will do this like 6 bags in a row. Then I'll throw a bag down, and I can continuously reload out of that bag indefinitely. 

Supply bag is glitched for squad and teammates as well. They'll just not get any ammo out of it half the time when I toss it. Battlefield 6? More like Bugfield 6. 

The damage doesn't reset for me. But the revives does and that's "normal". The challenge is 75 revives in 1 game, so it resets

Same here, stuck at 327 of 2000

I was trying breakthrough a lot, switch over to another mode and it started registering again, give it a try, if you keep playing same mode, try another one.

Well I did it. Battle Angel am I. 

Go play domination. Seriously. 

Spawn, sprint to enemy area, pull launcher out... launch a grenade into their chest. Die Repeat. 

I was averaging about 100-150 points per round. Fastest way to get this done I've found yet. 

Oh, I also had to restart the game in order for my red support badge to actually equip. 

Support Specialist Assignment 3 Not Tracking

I have been stuck on 92 out of 2,000 for days, having repeatedly trying.

I am using the SICH G1 WP launcher and hitting targets yet it's not working. I must be miss understanding the or the games seriously broken. This isn't the first challenge that isn't tracking.
