VMs Not Changing to Virtualdevice Even After Discovery...

So I've recently upgraded to OpManager 11.5 and so far I really find it to be a huge improvement over OM 10.x.
One of the great features is how, after you create a Virtual Host (Hyper-V in our case) it finds and acquires all VMs hosted on that machine, even the existing machines that were previously classified as "Server".

My problem is that not all of the VMs were acquired and re-classified as "VirtualDevice". I've tried to test the SNMP/WMI credentials and re-discover the VM, but even after a successful rediscovery, they still show "Server". Also, those VMs that show under the Virtual tab of the Host snapshot that have no IP addresses, are classified as "Server" when you add the IP.

They all have SNMP and WMI installed, configured, and opened on the local firewall so I'm not sure what's happening with these VMs.
