FORTNITE problem with stats

I really care about the fortnite statistics.
Recently I have played 5 games and I have gained a total of 15 killi. It showed me 3.00kd. Unfortunately, the fortnite tracker added 10 games to me, and I got smaller. I saw the history of the matches and found it as it should be, i.e. 5 arena solo matches.
Please correct this
