Hi Steve,
Thanks for using Ghostery!
If you see the trackers in the panel, then We have them in the library, but you have not set them to block. In this case, click on "Edit Blocking Options" and then check each tracker.. refresh the page and you will see them blocked.
Suggestion would be to make your global blocking options in the main Blocking Library in the options menu and then make page by page changes in the panel you have attached above.
Hope that helps!
