Charms not displaying anymore

I was trying to figure out why one of the transmitters was only reading 3.5V. Thought I set all appropriate properties on the charm and I hit Rebuild Hierarchy. Now I can't find any of the Charms that it previously show. How can I get this back?

Before I could see all of them on AMS Device Manager (Device Connection View). I would then double click DeltaV Network 1 and I would be able to see all my devices connected but now I can't. Is there a way to get back to this?
