DDP | EE Shield status as "Not protected" for policy-based encryption when SED drive is detected

Hello

I'm trying to troubleshoot an issue with PCs coming up as not-protected and I have noticed the entry which seems common among these not-protected devices:

DeviceEngine.cp: 3729 W]   ...One of the disks is SED

If this is coming up, the workstation doesn't come up as protected even after a month after having shield installed.

Is this the right assumption? How do I fix that with policies? 

Thanks in advance!
