vShield Edge "Applications"

Hello,

I have been trying to figure out how to add applications to the "Known Applications" list when creating a rule. I have found the option in Home -> Inventory -> Networking, then selecting the datacenter, vShield tab then clicking "Applications". I have added a few, however they are not showing up in the "Known Applications" list. I only have one datacenter so the scope is limited to the datacenter so I should see it.

Am I missing something here with my configuration?

ESXi 4 hosts running vShield 5.

Thanks,

Andrew
