I turn screen on, the running apps menu displays instead of home screen?

Okay, this is a little thing that for whatever reason is driving me bonkers. Bonkers I tell ya!

I recently updated to 5.1.1. Stock, but rooted and unlocked. I then installed xposed and some modules. I changed a lot, so it's hard to narrow down what is causing this.

When I turn my screen on, my main home screen should show up. You know the button on the bottom right that brings up a list of running apps? That's what shows up instead. So every time I turn on my screen, I need to hit the home button first. Bonkers I tell ya!

Thanks in advance!
