Sample listings how to edit the visibility?

Hi there,

I wanted to set up a couple of the classified listings that are private and not open to the public. I know you can edit the (Visibility: Public Edit) in the publish box. However, when I press the edit button it automatically brings the screen down to the (Listing Options) Where it then lists -Details Images Membership Access- with the save changes button. But I do not see where I can edit anything? It shows the tabs with Details, Images, Membership Access but it shows nothing for me to edit?

I would like to have a sample ad that is private and can only be shared if I send the link to someone. I don’t want it to be searched or have it show up to the public or on the front page. Can anyone help with this? Thank you.
