That RHEL bug also mentioned this problem only occurs on KDE, and not Gnome.

Once I made the configuration change noted above and started firewall-config I found that a few services were checked that were not supposed to be checked. I verified that they were indeed enabled in iptables. I have no doubt that got checked when I was attempting to figure our what was going on. Unchecking them did remove those rules from iptables, so I can once again configure server firewall rule using the GUI. Now all there is to do is verify the rest of our server's firewall configuration. Thanks!
