Support Specialist - Incendiary Airburst Launcher Damage Not Being Counted

While playing support, I've been using the Incendiary Airbust Launcher for the Support Specialist last challenge. I've been using it in the last few games, but the damage from each game is not being count. Sometimes it does, but sometimes it does not. Additionally, it is not counting all the revives from each game either.

Does this count for Conquest or is it specific to other game modes?

Thanks!
