That makes sense: the old iptables service installed several default chains, and firewalld does as well, but they’re not named the same, and I doubt there’s a 1:1 mapping between them.

That’s part of why I advised you to use one or the other, not both.  Another reason is that their persistent rule stores use entirely different file formats, in different locations.
