My kind of hero challenge not counting lightsaber kills

Same problem here. PC version. Killed over 15 players (actual kills not assists) as Luke in GA, then had 10 kills (again, not assists) in HvV as Vader. Still says I've not killed anyone even after exiting and restarting.

Seems like this game has a SERIOUS issue with timed challenges. It seems like every time a new one comes out there's some random issue with it not updating or counting correctly. Can you guys just rewrite the game from the ground up? lol
