Apex Legends bug RP

Hi. i just played a ranked match and crashed last minute (got second place) but when reconnected, all my progress from prior games was lost. I just cant. Why does my whole progress get lost when i have a crash?  Its obvious visible in the video, since my last game is seen as 190+RP and rank up to diamond 2 my current state shown is diamond 3 700RP which doesnt makes sense? WHAT is this. https://www.youtube.com/watch?v=E1PkAnlUdco Please review and let me know!
