SD WAN help

I have a fortigate 60e with 2 WAN lines coming in so I setup SD WAN with 50% volume on each and then set a SD-WAN status check and it shows as both WANs up. Then I changed my IPv4 policy instead of it been WAN1 to SD-WAN but now the internet wont work.

ANny ideas whats wrong ive followed guides but doesnt seeem to work oddly. Is there a step I've missed?

Switched back to just using 1 WAN for now but really wnat 2 so we have a fail safe if one goes down.
