Mac Studio Multiple Display Problems

Hope there's someone that may be able to shed some light on a rather odd bug I've discovered with the Mac Studio and Mac Studio Display which I had hoped was fixed with this update. Alas, it wasn't. The issue is: I'm running 3 monitors, 2 LG 5K UltraFine and the Studio Display. When the MAC goes into SLEEP and wakes, the Studio Display wakes earlier by a second or so and 'defaults the system into thinking there is only one monitor thus moving whatever was on the LG screens (open finder windows, open apps, open app palettes (Adobe CC) etc onto the Mac Studio Display. It's very frustrating to then have to re order the open finder windows etc. This only happens after SLEEP and not screen saver. If the Mac is starting from Shutdown, all three monitors fire at once. Can't explain it. Have tried Apple Care, nothing yet. Have moved the cables, swapped the thunderbolt ports, reloaded the software, trashed the prefs. Your thoughts?

I've just uploaded a recording of what happens to Apple. I'm at a loss to explain why. My guess is that Energy Saver has a bug, Secondly, I'd say it's the Studio Display itself. I'm having a friend bring his third party Thunderport Display over within days, I'll plug it in and use it as the third monitor and see if the problem remains. If it does, the issue is with the Energy Saver and the Mac Studio itself, if it doesn't do it, it's then obvious it's the Mac Display itself. Your thoughts?

Also, I performed a test this morning. I switched off the Mac Display. ONLY used the two LG monitors. It did the SAME thing. One monitor starts before the other. It’s not the Mac Studio display. It’s obvious it’s the system (Monterey) or the Mac Studio Ultra Max itself. I have used the LG UltraFine displays for more than six years with a late Mac Pro 2013 and never had an issue like this.

Have you unchecked in Mission Control found within system preferences the check box "displays have separate spaces."

I'm having a similar problem. Sometimes, when I wake my Mac Studio, some open windows will be resized, moved, or both. Happens frequently with Adobe apps, but also Mail, Messages, Slack, and Toggl.
