Service not working in firewall rule

Hi,

I am trying to create an endpoint firewall rule that allow traffic to DNS server on port 53 but it seems like the predefined "domain-udp" service is not working.

I have these rules atm

The strange thing is that connections to the servers does not work on rule 0 "DNS" and hit rule 1 "DNS 2", checked the logs on the client and it is port 53 protocol 17 (UDP) so it should hit against domain-udp but doesn't.

This is on EPS E84.50.7526, management is R81 cloud

Is there something obvious i might have missed that explains this behaviour maybe?
