Reassigning to firewalld as the description mentions that ufw is disabled. This is not a bug though because iptables relies on certain tables/chains being used and it looks like firewalld doesn't use those (which is fine for firewalld to do). You should be able to see all netfilter firewall rules with 'nft' but you'll only see rules that are added to the (now non-default) tables/chains that iptables expects (INPUT, OUTPUT, etc). More specifically, 'nft' will see the rules that 'iptables' creates but not necessarily the other way around.
