De Ranked After 2 Pip Game

Axterixa

I play DBD on Nintendo Switch and I keep getting to level 8, but the game puts me back to level 9 when I should be ranking up to 7? I just got out of a 2 pip game, but my rank became 9, I previously had 3 pips, so I should've leveled up, not down?

I dont know how, if possible to replicate this. However, it happens whenever I'm level 8 going on 7 and it puts me at a 9.
