Dual displays - dock is shown on the wrong display

[Chris Martin]

I have 2 displays
primary 30" dell
secondary 20" dell

In settings->screen-displays I have the primary screen set as the 30" Dell
BTW the 20" dell is incorrectly detected as a 18" display

However in settings->apperiance I have to set the put dock on the 20" Dell to get it to appear on the 30" screen. and vise versa. If I specify the 30" Dell for the dock, it appears on the 20" dell display
