[ovirt-users] Unable to export VM from data storage domain.

I'm running oVirt 4.4.4 with two data storage domains. One domain is where the production VMs run. The second domain is where I make backup copies of the VMs in the event of problems with the main production VMs. I make backups using the export option from the GUI's dropdown list. I just now tried to "restore" a backup copy via the export function and get an error. In fact, I get errors trying to export (import to my original data domain) any of the VMs that were exported to my backup data domain. My backup domain is a DATA domain and not an EXPORT domain. The exact error is: Export VM Failed [Cannot add VM. Cannot find a disk profile defined on storage domain 246c69e9-6f16-489f-8022-8613f6c1c22a.] Is this a bug or am I doing something wrong? Help is needed urgently. In advance, thank you.
