Hi,
I tried to change the number of lines and columns while running with the SwipeUp and SwipeDown gestures but the old grid appears in the background and stacks as you’ll see in the pictures. I can’t post more than 1 picture because I’m new so I uploaded them here. https://postimg.cc/gallery/zyyHy7M
I’m cleary doing something wrong but I can’t figure it out. Can someone help?
