Shareaholic buttons not appearing

Hi!
I have downloaded the updated version of Shareaholic, along with Google XMP sitemaps. I have customized the Shareaholic so that it only shows up in the post section. One example of a post: http://austinhometeam.com/austin-home-sellers-should-you-accept-a-va-loan/

The plugin worked the day of installation but disappeared the next day. I can’t figure out how to make appear again. I am not sure if this has anything to do with the Shareaholic plugin but I deleted the Google XMP sitemap the next day because WP engine does not allow that plugin.

If anyone has any idea of what’s going on, please help! I really like Shareaholic and would like to use it again.
