GRAW 2 problem.

I can't believe this! I don't play Graw 2 that much online, but I was playing today.
I was on rank 2, with it saying 58% till next rank. Fine. 

I played a ranked match, at the end of it, I quit. I went to leaderboards casually to check how far I was till next rank, and it says i'm on rank 1, with 8%!!!!!!!!

 What shall I do?
