Progression - NVO-228E

Hey there,

I've been having issues with tracking on weapon challenges, specifically for NVO-228E. It seems, from online research, that the in-game progress tracker is describing the wrong actions needed for the unlock. It says to inflict damage 0/300 (I'm stuck at 171.) with Assault Rifles, however, it seems you actually need to get 300 kills. 

Is there any chance this can be confirmed?

Thanks ahead of time.
