Failover object missing in traffic group

Hello Folks,

When we cannot see an object within failover objects and how to add it manually?

I have a VS, which isn't appearing in Failover objects. And strange thing is, for that specific VS, traffic goes to standby appliance and that is actually processes the traffic. As a result the VS servers intermittent services and looses the connection and functionality anytime. I have tried creating a new VS, however that behaves the same way. And again that VS is not reflecting to failover objects.

Any clues?

Thanks,

Darshan
