Simos, GNOME Software keeps running in the background. After updating GNOME Software on Ubuntu 16.04 LTS, you either need to log out and log back in or run a command like:
pkill gnome-software
On Ubuntu 18.04 LTS, GNOME Software should recognize that it has been updated and it will prompt you to restart the app so the above workaround isn't needed.
