Adrenaline Injector challenge not tracking

I'm still having issues with this challenge.  I just spent the last 2 hours focused solely on doing this challenge.  I see the white border around the edge of the screen when the adrenaline is active, so I know I'm getting kills during the active time.  But less than 1% of my kills are counting as adrenaline kills.  I still don't have the deploy beacon because this and I can't do the weekly challenges. Frustrating!
