Problem with desktop names and 3 monitors

I’m having an issue with TotalSpaces 2.8.12 on a Mac mini with macOS 10.15.6 and three horizontal monitors where, every time I wake my machine from sleep or reboot it, the two lateral monitors get switched, as far as TS is concerned. So, say I’ve named the monitor on the left “Left” and the monitor on the right “Right”, when I wake up my machine, those names will have been flipped and the apps that were assigned to the left-hand monitor will now be assigned to the right-hand monitor, and vice versa. I’ve tried renaming the monitors and reassigning the apps but it’s pointless, as it always flips, without fail.

Is this a known issue? Is there any way to fix it? Thanks.
