Cannot Add New Windows Display to Xibo CMS

I have a list of displays that exists on my Xibo/Displays page that I added months ago. However, in the past month when I add a new client even though it says the display is authorized and active, I cannot find it on Xibo/Displays page. I tried to see if there was a filter that is making the displays invisible, but that was not the case either, I manually cleared all of the filters. Please help.

It is solved!!!
Just noticed that the hardware key was duplicated across clients because I cloned the devices to each other. As soon as I erased the key and reconnected it was okay, I had to authorize and change the display name on the CMS side.
