FileVault 2 Enabled User Set. but FileVault 2 Partition Encryption State: Not Encrypted

[user-IUsJxvLxeb]

I have had users follow the Apple procedures to enable FileVault 2  but on a few the Partition Encryption State still shows not encrypted even though than the users ID is showing as a FileVault 2 Enabled user.   Also of note there are no other local accounts on the system.  Any thoughts on what might be causing this?

I'm also experiencing the same thing.

I also see this on a few devices in our Jamf Pro cloud instance. Essentially this is what we see, and the user gets prompted for credentials as if it's asking for FileVault to be unlocked.
