Workspaces doesn't recall correct on Mac

I’m trying to create a set-up with three monitors, Cubase 10 on Mac. Saving the set-up as a workspace should mean that I can recall it, but it doesn’t work that way. Apparently Cubase is okay with 2 monitors but the 3rd is left out. So a MIDI editor window opened on monitor 3 is hidden behind the window on the main monitor!!!
I searched on the net for an answer and guess what; I found my own post from 3 years back asking the same question!!!
I don’t understand Steinberg!!! I don’t how many issues I have with Cubase and I keep reporting and creating support tickets and NOTHING happens.
“So Tired” to quote Eric Clapton!!!

What is your setting in the system preferences for “Displays have separate Spaces” in the “Mission Control” tab ?
If it’s off, turn it on and see if it fixes this issue.

Yes that works. But I have to get used to this new set-up of the monitors, I will try it.
