GPO WMI filters are failing

Question

In Group Policy Manager when a WMI filter is created an error message is displayed:
Either the namespace entered is not a valid namespace on the local computer or you do not have access to this namespace on this computer.  It is possible this is a valid namespace on the remote computer)s).  If you wish to use this namespace, press
OK.  Press cancel to choose another namespace.
I am signed on as the domain administrator.  This domain is Server 2012 R2.
The namespace is the common root\cimv2.  When the browse button is pressed many namespaces are listed.  The error occurs no mater what namespace is selected.
Even if the error message is ignored and the wmi filter is created.  For windows 8 clients, wmi filters fail even though they should pass.
Select * from win32_operatingsystem where version like "6.%" will evaluate to false.
This is happening on two Server 2012 R2 domains.
Has anyone seen this?  Is there a fix?

Hi dga_1,
Before going further, would you please let me confirm something?
Please run the PowerShell command (gwmi -namespace "root" -class "__Namespace" | Select Name) to check if the
CIMV2 was listed.
Meanwhile, please go to Event Viewer and navigate to: Applications and Services Logs-> Microsoft-> Windows->
WMI-Activity. Then select Operational and check if you can find Event 5857 and 5858.
Based on current situation, please refer to the following article and troubleshoot.

Tips
By the way, I find you want to apply the WMI filter in Windows 8 client. Please use the
WQL Query Statement:
select * from Win32_OperatingSystem where Version like "6.2%" and ProductType = "1"
Then ignore this warning again. And use gpupdate /force to refresh group policy. Then run
gpresult command to collect report and check if this WMI filter still can’t be applied.
Hope this helps.
Best regards,
