Make sure your authors have entered their Facebook page URL under in the WP user profile, and they have allowed followers on Facebook.
From the Setup Guide (found in the SSO menu):
Authors should take a moment to update their Facebook Follower Settings to enable a Follow button on Facebook. In this way, authors can publish both private (for friends) and public (for friends and followers) content on their Facebook wall. When an author allows followers, Facebook will also link an author’s name in shares to their profile page.

This is an invalid tag – it’s not from WPSSO. You should remove it:
Extraneous Property Objects of this type do not allow properties named 'DC.date.issued'.

BTW, if you want https URLs, then make sure WordPress is configured to return https URLs. 😉 Right now, it appears that the WordPress get_permalink() function returns http URLs.
