Updating the "by" hovercard

I am using the social publisher to post to my personal, public Timeline. Everything works fine, except the “by” line under the title of the blog post reveals a “hovercard” with outdated information (on my FB timeline).

I believe the “by” line links to the post author’s author page (or archive page if the theme does not support author pages). That’s great, except I have updated my author pages, and the “hovercard” that FB displays on my Timeline still shows information that is a few days old.

Is there any way to get this updated in Facebook? If the above description is confusing, feel free to visit my public Timeline to see for yourself: /mickeydeagle
