My marksman kill shows longer kill

Hi!

I've had some issues after one game on Operational firestorm. All my kills disappeared with my scores and K/D, plus my marksman kill showed 1924m as longest, that I NEVER achieved. I only hit 1019m as a record. My kills are back, with the scores and K/D, but my marksman kill still shows 1924m. I'd like to get back my original achievement of 1019m please. 

I play on PS5, my EA account is linked of course. 

Thanks for the help!
