That UUID provided by essentials might be the offline mode UUID.
If the user is a premium user, it is intended to forward premium UUIDs to backends.
If the user was a cracked user and then switched to premium, but never logged back in after switching, essentials would show the last UUID of the player.

Also, premium UUIDs are not case sensitive but cracked once are so Milkthedev and milkthedev would have to different cracked UUIDs but the same premium UUID
