Firewall rules in [cellular] group are not applied

General

I’m trying to set up firewall rules that according to the documentation should only apply to mobile network, but I can not get them deployed. They do not show up in iptables -S command.

For example this kind of rule is not applied:

[cellular]
IPv4.OUTPUT.RULES = -p udp -m udp -d 1.1.1.1 --dport 53 -m conntrack --ctstate NEW -j ACCEPT;

I am using the latest 5.0.0.71 version of SFOS.
