Pi-hole not working on one device, rest is working fine.

As you describe it, your router is distributing it's own IP as DNS server via DHCP to the clients.
From a quick search, you can't change the IP distributed as local DNS server to something else (you would want to distribute Pihole's IP).

Your'r only option seems to be to disable DHCP on your router and use Pihole as DHCP server if you want to see each individual client in the query log.
