Firewall rule not working for subdomain

My sub-domain is added to the DNS tab of Cloudflare Dashboard.
Also have content on it.
Nevertheless, it is too :orange: (proxied) the same as you stated.

I used for testing purpose:

(http.host eq "sub.mydomain.hr" and ip.geoip.country in {"HR"})

With action “block” and as far as I am from Croatia, I got 1020 Access denied as it is supposed to be and working fine.

But, in which position that “block” rule actually is in your list of Firewall Rules?
