Issues with class challenges

I have issue with the tracking of several class challenges:

1. Assault expert mission 2: Tracks the incendiary round shotgun damage once in a full moon. I have killed and caused incendiary damage to at least 50-60 players. So far it has tracked 225/5000 damage.
2. Recon specialist mission 2: The mission to laser designate targets that sustain damage does not track at all. I targeted both  air and land targets and watched them getting destroyed and so far it is still 0/2000.
3. Support Specialist mission 3: Damaged tracked so far is 14/2000. So far i have burned players for hundreds, maybe even thousand of incendiary damage  and as you can see it track pretty much nothing. Obviously it works intermittently as point 1.
