No such issue on a clean test install.

[root at centos7 fail2ban]# rpm -qa fail2ban\*
fail2ban-sendmail-0.9.3-1.el7.noarch
fail2ban-firewalld-0.9.3-1.el7.noarch
fail2ban-0.9.3-1.el7.noarch
fail2ban-server-0.9.3-1.el7.noarch

Make sure you have fail2ban-firewalld installed as this provides the 
configuration to use firewallcmd-ipset as default banaction.

Plenty of reasons for the "ERROR: NOT_ENABLED" logging, see man 5 
firewalld.dbus.
