NAV Connection Blocking "Action" - Grayed Out

The "action" column in NAV (which tells me whether NAV allowed or blocked a connection) is not Red or Green.  It's gray, and the information in all the other columes is present (ie.,  it is in-bound traffic, safari.app, remote port 80, and a mysterious yahoo.com  IP address.) and saved by NAV.  How do I interpret the action of NAV?  Was the connection allowed or not?

 

P.S - why does Symantec you keep trying to store a 1MB test html cookie file on my computer?  Please stop it!!!!
