Killtracker not working properly

[ma9ici5n]

I noticed this a few times. Let me explain what happened:

I had 50 kills on bloodhound before a match. After the match it told me how many kills i got, lets say 2. I expected to see 52 on my kill tracker but it sayed 51. A few times i thought, ok then I just falsely remembered the kills I've got. But yesterday it became really obvious. I played a game with Blangalore. I had 0 kills before the match and in the match i got 2 kills. (not knockdows, I know how it works. in the end screen there was written 2 kills). After the match I looked at my tracker for Bangalore and voila, only 1 kill was tracked.

I attached a picture showing my issue. Maybe I am just not understanding something but I think this is a bug.
