League points bugged?

Hi Riot. I have a bug to report. I was this morning placed in Bronze 1, 0 lp (Dont hate on my elo please), After i logged out, and logged in again, i had -1 lp. I didnt play any ranked games, so i was confused. I tryed to log out and in again. This time i was -6 lp. I tryed a last time, where i ended up at -10 lp. I dont know how this can happend, but if someone know a solution, pls tell me :)
