Hello Mike,
I have no problems with my MacBook Pro M3 max and my MacBook Air M4.
The arrangement of the monitors will not change after sleep-mode.
Maybe this depends on how to connect the monitors to the mac? I have a thunderbolt dock where my devices (PSU, monitors, harddrives and audio-interface) are connected, so I have to connect only one cable if I use the other macbook.

But no matter how I arranged my monitors it had no effect an the collapses with the track divider, maybe I didn't set it up to what Andrew said.
