Overall KD not workin correctly for hardcore players

I only play hardcore also. I usually have at least a 2.0 KD in games, sometimes higher. But ever since the patch my KD has dropped daily. My kills never go up anymore. It says I have 1,238kills for the past week. I get about 150 kills per day but my kills still read at 1,238. This is BS and they need to fix it. Or just reset it to zero so I can start my KD all over. Either way I hope they fix this soon!! And they need to make hardcore lobby's a option as part of the multiplayer lists.
