Problem with Firewall-Diagram (Country)

Doing mostly updates and new adiustment to make my IPfire more harden , I notice that when I go to Firewall-Diagram (Country) I only see hit from green they all are to the port 53 is this normal or am i missing something?

I am using Proxy on most device that can use proxy on my network.

Is this because i am using proxy?
The port 53 is DNS port I understand is this because I am using Recursor Mode?
