physical interface not "seen"

Hello guys,

I have just installed Sophos XG firewall for home use. My hardware is Asrock H270M-ITX/ac motherboard with a Intel Pro 1000 VT quad gigabit pord card. That is 2 gigabit ports from within the MB itself and 4 gigabit ports from the Intel NIC - a total of 6 ports. And besides this i also have a wlan interface, but this is out of scope.

The problem as i see, is that Sophos recognises only 5 gigabit ports out of 6:

This build is completelly new so i had to check it with other OS to see another perspective. I booted from a linux stick and this one sees all the correct 6 physical gigabit interfaces:

So why Sophos doesn't see all the ports and how can i get it see all the ports?

Thanks
