Refresh device

So i was needing to do a device refresh on some devices..  I clicked on one extra group so i hit cancel on the job box that popped up and not OK since I needed to go back..  now if I try to do a refresh on the correct devices i get an error on top of the screen

Failed to create quick task as another task of the same type is already active on one or more of these devices.

why is the other job stuck when i canceled it and didn't hit ok.
