How can I clear errors from systemctl status firewalld output?

Issue

• When entering firewalld rules some typos were made which resulted in errors being logged to systemctl status firewalld. We'd like to clean up this output and have the errors removed.

[root@rhel7u9 ~]# systemctl status -l firewalld
