Default [Q] Gallery app has lingering auto backup album

I have an auto backup folder still lingering in my Gallery app even after deleting everything that was auto backed up in Google+ photo albums. Those images no longer exist. If I attempt to download those pictures from the phone it says failed to download as they aren't available. Why are they still showing up and how do I get rid of this from showing up in the Gallery app? Google+/Photos apps do not show these pics/album or when viewing at the pictures on the website. Any ideas?
