Device settings issue

OK so the Nokia 5G21 gateway. I am running firmware version 1.2201.00.0324 and it reports "20" devices online but I have W10 laptops, MacBooks, iPads, phones, Xbox, PS3, WiiU, Switch, and 5 Linux clients, Harmony hub and AV receiver that all appear at one time or another but no cameras or garage door hub etc… so the web GUI reports 20 devices but it only states that. It will not list them. When I run a scan I can see the currently active 12 clients.  The T-Mobile HI mobile application will list the devices when it works but well that is when it feels like working which is seldom and the listing is not super informative. I do all the gateway management with the browser or my iPad Pro but gave up on the mobile application. I use a IP scanner or Zenmap on my MacBook Pro to scan the LAN for active IP addresses and both works great. If you want to find the active hosts on the local network, IP Scanner is easy and fast. Zenmap can be more verbose and will list the open ports etc… handy to see what is going on. The web GUI interface seems to keep track of the number of clients but does not solo limit the count to what is active. So, the device reporting is a bit sketchy.
