Stats weren't tracking my first 30ish games

My kills and score +others weren’t being tracked before May 24th. I was frequently checking my stats waiting for my kills and score to finally show but they didn’t link up to how many I would have had, they just started counting from 0 on my ~30th game. But my matches have been showing so my kills/match is lower than what I was wanting and I was hoping to grind the leaderboard.

I know for a fact my kills aren’t up to date since it says I have 6 rifle kills where the first two days I was pretty much only using the MK 20 SSR.

Would like to know if this is possible to fix.
