Class ranking glitch in Battlefield 1

[FRONTLINEFOX20]

So I just spent a long time grinding the pilot class to rank up to Pilot rank 10 so I could unlock the M1911 with the stock and extended magazine. I kept checking how close I was getting and then in my last game a few minutes ago I reached rank 10 and unlocked the gun. It showed that I had at the top of my screen. But then the game ended and it said I’d reached rank 5 which was completely wrong. It reached rank 10 and then it threw me back to rank 5 and locked the gun again. Is there any way to fix this or am I just screwed and have to grind it all over again?

@FRONTLINEFOX20 Hey, can you play a few matches if you haven't already? It should come back on its own if you just play as normal.

I have but it’s not back yet. I’ll keep playing though. After I posted the original I also got a cool skin out of a battlepack for one of my favorite medic rifles and it just upped and vanished. I didn’t scrap it. Hopefully it all comes back though.
