Kivy RecycleView data widgets showing up on top of each other

Im trying to make the list of this custom widgets be in a vertical list above and below each other but they all appear in the same pos.

Im not sure where im going wrong. I’vw tried a few little things that I could thnk of, but clearly, to no solution.

I’m new to kivy so any tips you may have would be awesome.
