I've recently taken a closer look at the SD-WAN route settings. In the Help section it states the following:
The heading in the SD-WAN section states that the default route is SD-WAN > VPN > Static

For IPv6, I notice that there is no Internet IPv6 Group. I suppose that means that I will need to create one based on the following link:
