Content mismatch: Missing embedded video

I have no video on this page and I am getting a missing embedded video error. I HAD a video, but it has since been removed.

When I try to add this script to the header of the plugin, it affects all my amp pages, because, of course, Javascript is not valid for AMP.

<script async custom-element=”amp-youtube” src=”https://cdn.ampproject.org/v0/amp-youtube-0.1.js”></script>

I am nervous every time I update this plugin.
