IPV6 on WAN even after electing no IPV6 in config

[tdalej]

Even after explicitly configuring no IPV6 on the wan, I still see a DHCP6 entry online for the WAN in the "Gateways" widget on the dashboard.

(Clarification added in edit)
   I'm setting up OPNSense in parallel to another firewall in order to shift to OPNSense.
   I configured the WAN interface during the CLI setup at install time and specified no IPV6.
   On first boot after that I disconnected the WAN interface in order to not conflict on WAN, leaving only the LAN connected in order
   to configure OPNSense.  With the WAN interface disconnected, first boot seems to have overridden the "No IPV6" settings.
   I'm using pppoe  on the WAN interface if that makes any difference.
   Once logged in, I have been able to disable it again from the Admin GUI.

   Just seems like disabling should mean it's disabled - no matter where you do it.

Even though setting it up for no IPV6, it's still there -- is that by design or is this a bug?

(It would be a lot easier to show this if the forum allowed image attachments!)

How do I get rid of this, given that saving a specific configuration setting of no IPV6 doesn't seem to actually happen?
