Mandatory boilerplate incorrect

Hello, I’ve been unable to get the basic AMP generation working properly; the AMP validator tells me the mandatory CDATA text inside head > style[amp-boilerplate] is incorrect. The page seems to generate fine but it’s not passing muster with the validator and thus not getting served up to mobile users.

Example page: http://immortals.gg/news/2016/09/13/reignover-heads-to-korea-to-support-clg-boot-camp/amp/

Any suggestions?
