[xmonad] Polybar covering on top of windows

Hi! I've been using xmonad for a while now but since switching to Polybar I can't get windows to hide the bar when toggling struts. I'm on xmonad 0.13 and here's my configuration: https://github.com/tjarvstrand/.cfg/blob/master/.xmonad/xmonad.hs Would really appreciate some advice! Thanks Thomas
