Problem with window arrangement on multiple monitors

On the last PC, when I changed shotcut window arrangement on multiple monitors, and then closed the app, and then reopened them everything stayed in place, now it all moves.
Also when I start to move the main Window around all other windows start moving around and decreasing in size.
Can somebody help me this is so annoying, especially when I know it’s probably only one option that I can’t find? I clicked through all of the options that I could find.
