Found Kills Glitched?

I got found kills 2 times and the challenge didn't pop. The first time I just found the weapon and the second time I killed a guy and took his weapon and killed 5 more times. I know I got the right number of kills because bloodthirsty showed up on the first one, and another kill after bloodthirsty the second time.

Is it because I was playing Kill Confirmed?
