So in LAN/DHCP Server/"Manually Assigned IP around the DHCP list" I was adding mac addresses and hostnames. But every device I added had the name "New device" above the mac address, but on the right under hostname I did see the hostname I added. When I clicked on the default icon of the computer I could change the "Name" and I could change the icon but when I clicked on "Apply" it didn't take. Every device is listed as "New device" and I can't fix it.
I also know if you go to Network Protection/AI Protection/Parental Controls and try to add a device to "Web & Apps Filters" and select the mac address. Eventually you'll see "New device" again and any attempts to change it there also fails.
