if run code (just copy , paste python file , should work if have kivy installed), select '1 week' dropdown menu load 1 of these 'recipe blocks' i'm trying create, 2 things go wrong. firstly, checkbox not clickable @ all. cannot change state. secondly, label of 'test' label @ top of scrollview should have blue background doesn't show @ all. believe both these issues scrollview/grid can't sure. ideas should do?
