[CentOS] centos8 :: firewalld active but tables empty

Hi! I have a minimal installation of centos8 + packages for freeipa as a 
vbox vm. there is something strange with the firewall rules :

[root at ldap ~]# iptables -S
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT

[root at ldap ~]# firewall-cmd --get-active-zones
public
    interfaces: enp0s17

[root at ldap ~]# firewall-cmd --state
running

[root at ldap ~]# firewall-cmd --zone=public --permanent --list-all
public
    target: default
    icmp-block-inversion: no
    interfaces:
    sources:
    services: cockpit dhcpv6-client dns freeipa-ldap freeipa-ldaps http 
https ssh
    ports: 22/tcp 60000/tcp
    protocols:
    masquerade: no
    forward-ports:
    source-ports:
    icmp-blocks:
    rich rules:

Does anyone know what is the problem or how can i fix this?
Thank you!
Adrian
