Norm Match Making Recently

I don't understand what's going on recently but I've been playing Norms and all of a sudden I'm getting very low level players in my Que like 10-20s and they always seem to be in a duo. I've never gotten such a weird level discrepancy before unless I was with a friend leveling a smurf. I know that Norms have a separate set of MMR but I doubt my MMR is that low to even warrant the level difference. Am I doing something wrong or did I miss some update?
