Newbie to VMWare - question about DVS configuration viewing

I am able to see my Distributed Switch networking topology from each host in my cluster (8 hosts).

However, if I try to view the configuration topologies for each Distributed Virtual Switch

in the Home -> Networking tab, I get a "vim.fault.NotFound" error. It just keeps "loading".

This occurs if I go to Ports tab as well. Now, this only occurs for one

of the Distributed Virtual Switches I'm employing (3 total). The other 2 show the topologies fine.

Any ideas as to why it's not showing in the Home -> Networking area?

Thanks!
