Cannot Reassign Virtual Desktop in Windows Server 2012 Personal Managed VDI Collection

Question

I have a Personal Virtual Desktop Collection on my Windows 2012 server with 3 desktops created.
For testing purposes, I assigned the 3 desktops to admin users and everything was working well. I need to re-assign two of the three desktops to the actual end-users now that they are setup the way I want, and tested. I go through Server Manager - Remote
Desktop Services - Collections - Virtual Desktop and select the virtual desktops, then select Assign and enter the new AD User. It does not error, and now shows the right user assigned.
But, when I try to remote desktop for these two users, it logs into the actual Windows 2012 server, and not the virtual guest on that server.
I've rebooted the server and guests a few times, and cannot seem to get this working for these two users.
Any ideas?
