Public Icmp/Icmp6/UDP [block] rules keep reappear in firewall packet rules

[REDACTED]

I'm trying to get rid of this [block] rules in [firewall]-> [settings] -> [packet rules]
but they reappear after computer reboot.
I delete them. I check then if they are deleted and it's ok. But after reboot i have go again to packet rules and delete them.
Is there a way to stop this block rules regarding Public Icmp/Icmp6/UDP rules reappear ?

I run several servers (https, mail, udp load balancer, etc) and I need access from outside world etc etc etc

Pretty pls ?
Thx
