I only see two, the main and the one external that is acting as I want.
I should add I am using a Targus USB docking device that is DisplayLink enabled

I have the same problem.
When I connect a SECOND external monitor via USB (DisplayLink) to my MacBook Pro, it mirrors my primary monitor. I cannot configure it as a desktop extension. Only the first USB (DisplayLink) monitor will function as a desktop extension.
MacBook Pro (13-inch, Mid 2012)
OSX High Sierra 10.13.6 (17G65)
