Firewall complains in syslog

Current Behavior

Had a running firewall configuration, and just enabled ssh on the wan zone:

admin@bpi-07-c5-3f:/config/firewall/zone/wan/> set service ssh
admin@bpi-07-c5-3f:/config/firewall/zone/wan/> leave

but show firewall seems correct:

Have seen this previous when configuring the firewall as well.
