Do you have the "Private Wi-Fi Address" feature enabled on the iPhones? If so, your iPhone is generating a "random" MAC address and it makes it hard to identify the phone.

And further to that point, your home network is trusted, so no need to use the randomizer there. 

Go to each iphone. Select "Settings" and then "Wi-Fi" and click the circled "i" (for information, next to your nextwork name - SSID). Match the Wi-Fi address of each phone to the MAC address that is displayed in SHM (when you select the device in SHM).
