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.

I got it working correctly. All I did was change some of the layout stuff in the .kv file. I'll post some of the .kv below. The only real change I made in the .py was changing the YT_Widget to extend from the BoxLayout class instead of a FloatLayout, not sure if it had any effect on this problem.

Anyways, the situtation has been corrected. Thanks. :)
