So, I wanna know that why does it shows 6 kills in front of my name (I am the chamber by the way).

I dropped an ace in that round and then dies to the spike (The time was less and I was not able to return to safety.)

So, does anyone knows that why does it shows 6 kills there instead of 5, did my suicidal act also counted there?

I dropped a 30 in that match, ~~typical chamber stuff,~~ and the opponents were around lv 100-150, I am lv 84 right now (83 at that time) and there was a single lv 128 (maybe) in our team and other new players. Thanks to RIOT matchmaking.
