My kills are not registering for the armor module. Example- I will use armor enhancement and at the end of the game I will get nada even after 10 or so kills. I tried using another(different) armor perk and same thing, points wont register. Anyone else having similar problem. I am level 19 and armor is 5, power 7, stealth 7 almost 8.

So many glitches, so little time.

I haven't had your problem, but my friend says his stealth enhance won't level up.

yeah i have noticed the same as you but it seems intermittent.
I also noticed that i got my Gauss attachment kills without actually using the gauss but just having it attached :s

well i did somemore testing and if you are in stealth and goto max armor it wont work. If you go straight to armor mode it seems to. So i guess i cant cloak then jump to max armor.

Same thing here with the stealth enhance. Only way i get credit is if i cloak and immediately stealth kill

I don't know if it is a glitch or not but it does the same thing for all attachments like the Reflex Sights, under-barrel Shotgun and even the Gauss.
