openmediavault-luksencryption; no devices

Release: 4.1.10
openmediavault-luksencryption 3.0.3

I have a single 3TB internal hard drive that I would like to encrypt. I've installed the plug-in, but when I try to select a device, no devices show. My internal HD is listed under Disks and File Systems shows it as unmounted EXT4. When I try to Create and Select a Device my internal HD doesn't show. Any idea what's going on? I am stumped.

Cheers

@ryecoaaron Pfff... that was embarrassingly simple. Thank you kind Sir. Cheers
