Network name doesn't change

After upgrading to 2.118 via the “System Update” menu option (which was a disaster, btw, as I ended up re-installing from scratch) I am trying to change the network to ‘music775’, to match all the bookmarks already on various devices around the house. But the name change doesn’t stick. Here’s a screen grab after multiple reboots. Network name is set to ‘music775’ but I can only access via ‘volumio.local’. It used to work fine in 2.014
