HA menu bar/header stuck at bottom

Hi there. I have an odd problem–my menu bar is stuck at the bottom of all my views. I want to move it back to the top, because i want to add a floating navbar and currently the menu bar is obscuring it.

Normal behaviour is for the menu bar to be at the top, so I must have done something, but I cannot remember what. See image below.

I need some help diagnosing this. I don’t have kiosk mode installed.
