Multiheaded setup treated as one big screen

First off, this window manager is great. Very responsive, lightweight and easy to configure (props to the dev making the config file look a lot like i3).

But here is the issue I'm currently having: my current setup uses two monitors (a 1920x1080 and 1360x768) and when any tiled window is opened, it is streched between both of my monitors, behaving like one big screen.

How to reproduce: Use any xrandr multiheaded display setup.
