Be careful of how prefabs are demoed here
Putting UI together can be quite the challenge. I personally find that sometimes the same steps repeated when dealing with Vertical or Horizontal Layouts don’t behave the same way every time.
A good tip when editing UI prefabs is to turn the automatic saving off in the upper right corner of the scene view in a prefab editor. Save when things look right, and step back and try again when they don’t.
