I have a Mac Book laptop with Mojave. I use two desks (in different location) each having two Dell monitors that I connect via display port to the laptop.
It works well, however when I switch between my desks the desktop are mapped to different monitors. The windows and icons that were on my left monitor at my other desk are now on the right monitor, conversely the windows and icons that were on the right monitor are now on the left one.
Note that the display arrangement is correct, I can move my mouse from one screen to another in the same way that they are physically set (which is the same at both location).
Hence my question: how do I fix the desktop (which contains windows and icons) to screens to have the window placed in the same way regardless where I work?

It looks which desktop is map to which screen depends on the port the screen is connected to. The (retro) Mac Book pro that I have has two display ports. I must be consistently inverting in which port I input the cables from one location to the other.
