Policy route not being ignored if wan interface is down

Hi We have a problem using policy routes in our FG100D. We have 2 wan links, with static routes, same distance and priority We are using policy route to pass traffic from one of our LAN IP via wan2. Everything is fine until here. When we put the wan2 administrative status to down manually, the policy route always tries to route the traffic via wan2. According to this document: http://kb.fortinet.com/kb....do?externalID=100116, if the interface is down, the policy route should be ignored, but the fortigate is not ignoring it, and tries always to route traffic via wan2. We are only using 1 policy route. I use the same scenario in other other devices like 90D and 300C, but it is not working in this device with 100D. Any ideas?
