Displayed Rank isn't Matchmaking Rank

I've been grinding Legion (just started playing them and killer as a role yesterday) and I'm currently at rank 14. However, I keep getting matched with purple, green and red rank survivors.

When I ranked up to rank 14, I got the steam achievement for hitting rank 10. While that could be a bug, I actually think it means that the Devs assign you a matchmaking rank that's different from what's displayed on screen. So even though I'm rank 14 currently, the game is treating me like a rank 10.

Thoughts? (I'm a rank 9 survivor so yeah I had experience with the game before I started playing killer)
