xFirewall Can't Detect Rules Created via the GUI (Windows 2012/WMF4)

I'm running Windows 2012 (non R2) with WMF4. We have manually created some firewall rules using the GUI, and are now trying to detect and monitor these rules using DSC. When created with the GUI, the resources get a Name that is a GUID, and a DisplayName of whatever you intended the name to be. All the -NetFirewallRule checks in the xFirewall resource use -Name, so it is unable to detect the rule properly. A possible fix would be to have -NetFirewallRule check for either Name or DisplayName matches.

Output: Here's what happens when I try to Test-TargetResource:

PS C:\Program Files\WindowsPowerShell\Modules\xNetworking\DSCResources\MSFT_xFirewall> $parms
