SD WAN setup issue

I am setting up a Fortigate 60E with SD WAN for failover/load balance but running into an issue.

I have 2 WANs connected and both work individually with my ipv4 policy if I switch between them, so I know the WANS are setup correct including the static routes. When I add them into SD-WAN and then set my ipv4 to use the SD WAN I have no internet at all. I feel I must be missing something obvious but I've followed the guides I've seen like this

Any ideas would be appreciated
