Cannot Delete a Cloud from SCVMM 2012

Morning everyone,

I'm using SCVMM 2012 v3.0.6019.0 and having problems removing some of the clouds that were automatically created for the self-service users.  These unnecessary clouds no longer have any services/vms/storage/resources assigned to them, and all user roles/owners have also been removed.  But when I try to delete the clouds (VMs and Services -> Right-click on cloud -> Delete) nothing happens.  The job is created, and says it ran successfully in 0 seconds, but there's no result name on the summary tab and no information under the Property / Previous Value / New Value table.

I've tried reassigning owners and creating VMs then deleting them, as well as using remove-sccloud in PS, but I have the same (no) result using PowerShell also.  Has anyone run in to this and know of a way to forcefully remove them?

Thanks in advance,

David
