How Do I Delete Leftover Gateways from the DPinger Service

[kagbasi-wgsdac]

So while testing and configuring VLANs, I created and deleted a few and in the process, there seems to now be at least three of the associated Gateways now leftover in the DPinger Service.  However, if I go to Gateways, I don't see these listed.

How do I get rid of these entries from my dashboard?

System : Gateways : Single?

Yep already checked - the only entry listed is the gateway for my WAN interface.  So can't figure out why these are still lingering (even after I rebooted the firewall).

Via CLI open /conf/config.xml and remove the stale XML sections (make backup before)
