On a fresh install from at least Ubuntu 17.04 up to 18.10, when I change Settings->Dock->Show on to a specific monitor on a dual monitor setup, this setting gets flipped if I change the primary display in Settings->Devices->Displays->Primary Display.
For Example I have Monitor A and Monitor B
After a fresh install Monitor A is primary with title bar, clock, etc. and the dock. If I change the dock to Show on Monitor B it moves as desired. But when I change Primary Display to Monitor B also, the dock immediately goes to Monitor A again. When I check the Show on setting it still displays Monitor B but it's actually on Monitor A. Selecting Monitor A will move the dock to Monitor B.
