Nav Bar doesn't cover screen when opened

enter image description hereenter image description hereI'm building a registration form screen in Kivy. I have some other basic screens as part of the nav bar. However, this is the first one I'm really adding some content to. I have some round text fields that I've just thrown on there to get an idea of spacing, but currently when I reopen the NAV the bar the text field buttons appear in front of it and I want it to be behind.
