Displaying Two RecycleView Widgets Side By Side With Kivy 2.1

I am not too sure as to why I cant display two recycleview widgets side by side within a grid layout or box layout. Anyone have any ideas as to why ? I tried placing them within a boxlayout, gridlayout, and scatter but I can only get Step1 to appear. I tried adjusting the default size hint as well as a couple other parameters within the kv file. Do you think it has something to do with the screen manager. I am trying to really keep most of the display stuff within the kv file if possible. Do you think I should place it within the root widget on the python side of things?

Thanks !
