I updated two or three of the currently configured 5 sites in control center a few days ago from Joomla Core 3.7.1 to 3.7.2. This worked very well. Later, I accidentally noticed that an extra administrator directory had been created below the existing administrator directory and not have been removed. This didn't happen where I upgraded Joomla by directly logging in to the site, only where I did the remote updates.
The path that is left and is empty is: /administrator/administrator/components/com_joomlabackup
