Session Browser not showing Shared Server session

We have TOAD 11.5.1.2 and Oracle RDBMS 11.2.0.2. Take a look at the screen shot. We are in a higher ed environment and modify our init.ora to use shared_server during high usage periods such as registration. What I'm trying to figure out is why TOAD Session Browser shows "Server NONE" and "Status INACTIVE" on all the sessions.
