Trouble with displaying links icon in Ss4 Navigator

BeCommunities,

I am having trouble with displaying the links icon in Ss4 Navigator. Via Composer (View Attributes>Markers) turns the display of the links icons on and off. This helps a reviewer see if the link is a video OR a .pdf, thus helps them better decide what link they want to open.

Unless I am doing something incorrect, Navigator does not display the icons via the first attachment (Navigator) against the second attachment (Composer). Please see the attached images.
