SRX300 dual isp failover question

Hello all,

I have some SRX300 devices at a couple of customers and on all these devices we have failover configured.

These customers all have Cable and a DSL connection.

Cable is primary and DSL is failover/secondary.

When there is a error on the Cable isp the SRX300 is switching over to the DSL ISP

But when the Cable isp is coming back the connection is not switching back.

The only way to achieve this is to reboot the SRX300

services {
    rpm {
        probe probe-internet {
            test test-1 {
                target address 8.8.8.8;
                probe-count 3;
                probe-interval 2;
                test-interval 2;
                thresholds {
                    successive-loss 3;
                    total-loss 3;
                }
                destination-interface ge-0/0/0.0;
                next-hop 1.2.3.4;
            }
        }
    }
    ip-monitoring {
        policy test-1 {
            match {
                rpm-probe probe-internet;
            }
            then {
                preferred-route {
                    route 0.0.0.0/0 {
                        next-hop 5.6.7.8;
                    }
                }
            }
        }
    }
}

The ip adresses in the config above are not the real ip addresses but 1.2.3.4 is the next-hop for the Cable connection connected to GE-0/0/0.0 and 5.6.7.8 is the next-hop address for the DSL connection and is connected to GE-0/0/1.0

Is there something i overlook here ?

I am pretty sure this is all i have to setup
