Twentyfourteen Missing Updated Structured Data

Greetings! I’m using the core Twenty Fourteen theme and Google webmaster tools are telling me there’s an hatom missing: updated structured data error. I’ve tried to search for a solution and I found some references to earlier core WordPress themes but none of those solutions seemed to apply to the current Twenty Fourteen theme.

If someone would be kind enough as to point me in the right direction of how to fix this, I would greatly appreciate it. Thank you.
