At the moment i have around 102 kills using armor w/ armor enchance according to the skill assessment progress, yet i have 200 or so kills with armor enabled in the general stats. Now considering i've never used any other armor perk, that seems a bit off. Has anyone else been having trouble with this perk?

Its wierd i know, it show me the same thing. Its probably that you don't have armor enhance perk equiped and turned on everytime you kill some one in armor mode.
Or its another bug, i am realy not sure, i didn't count it kill by kill.
