Pretty sure the problem is that you’re using Offset for Positioning and Scaling. In the properties tab, switch from Offset to Scale (example: A Frame appears with {0,100} {0,100} as in 0 scale, 100 offset. Switch that to something like {0.1,0} {0.2,0}
This way it scales to the screen, and when you try editing the frame by dragging it, it will automatically use scale instead of offset
sadly you need to work a little on switching each from offset to scale
