Content Protection tab not displaying any avaialble shortcodes…

Greetings! Must be a silly “new person” question … followed install correctly (we think!) … including simple Level 1 and Level 2 Membership defaults as installed by PlugIn … but reaching the Options:Content Protection and, contrary to manual, etc., do not see any shortcodes in the “The shortcodes that are available to use are shown below.” area. Did I miss a step? Thanks for the help!
