Not Getting All RP points in Ranked

So I was wondering if this is happening to any one else? I just played a ranked game and got 6 kills. Death card was right and showed 6 kills as well. but when I get back into the lobby the after match report only shows I got 4 kills and only gave me the rp for the 4 kills. that's 16 rp per kill so I was shorted 32 RP which is half of my entry cost. and I usually que up from in game so there is no telling how long this has been happening. any one else experiencing this? or is this normal? it was 6 knocks and 6 kills. could 2 people have been revived so I "lose out" on those kills since they are alive in the game again? But, if that's the case why does it tell me 6 kills in game and on death card.
