In your current configuration, your clients never use Pi-hole, but rather your router at 192.168.178.1 as local DNS server, and your router then forwards them either to your Pi-hole's IPv4 address or to your ISP's DNS server IPv6 addresses.
You should change your router's local DNS server as distributed via DHCP (your 1.1.) to your Pi-hole host machine's 192.168.178.130, and leave the router's IPv4 and IPv6 upstreams with your ISP (your 2.2. Internet|Type of Connection| DNS Server).
