Adobe photoshop cc 2014 assign to desktop not working properly

Having an issue with Adobe photoshop cc 2014 not switching to my secondary monitor.

I currently have my iMac connected to a 22" cintiq monitor that I use as my secondary monitor and whenever I open photoshop I right click on the "Ps" icon in the tray and navigate to options > Assign To: Desktop on Display 2(the Cintiq) and photoshop doesn't move over to the next screen. I've tried doing this with application frame checked on and off in photoshop. When it's checked on it will move to the cintiq, when it's checked off it won't move.

I've tried to do the exact same things with illustrator and I haven't had any problems what so ever.

Has anyone had a similar issue?
