What happens when you ls -la on the containing directory? That should tell you the owner.
You're probably going to have to log in to the NAS and manage the folder, sounds like something on the device has taken ownership. It's hard to tell why, sometimes various media indexers can do funny things. I always disabled those on the Synology units I had.
ls -l shows me as the owner of all the folders on the drive. (I'm logged into the NAS already.)
And you can't delete the folder as root user on the NAS?
And you can't delete the folder as root user on the NAS?
Correct. I am the root user, logged into the NAS itself, and can delete other folders. I can also add folders. It's just this one that is being stubborn. :-)
