Back in November of 2015 I upgraded from 8.1 to 10. I run a two monitor setup.
The taskbar icons used to appear on both of my monitors, but now only appear on my secondary.
I've tried the option to have taskbar icons appear on all monitors. Doesn't work.

I should add when I move the task bar to the left, right, or top side of the screen the icons will appear on both monitors. But, when the taskbar is set to appear at the bottom, the icons do not appear on the primary display.

Any thoughts?
