Available storage not being discovered

I have 80 clusters (server 2008 R2) and an interesting available storage resource group issue, of the 80 resource groups less then 10 are being discovered as available storage and having the  default override applied to turn the monitoring off for these resource groups

Essentially they are all being properly discovered as windows 2008 cluster resource groups but they do not get discovered into the windows server 2008 available storage cluster resource group class which the override targets leaving me some 70 clusters in a constant state of alert

All MP's are bleeding edge(no updates available)

Any thoughts ?
