Posting Adobe Express Project to Facebook

I am trying to post an AE project to Facebook.  The project is published.  We are connected to the social media (facebook).  After clicking "add new" the dialog box comes up.  I can choose facebook, set the date and write some text.  When I click on the "add media" my project does not show up.  A few old projects show up there but not any current ones.  What am I doing wrong?

Thanks for the help.
