[Plugin: Facebook Page Photo Gallery] Can't get gallery to show up in post feed.

I lOVE this plugin. I’ve used it on several sites now, but I’m having issues with one where I’ve created a category, “Photos”, and I have a link to that feed. The WordPress template is “Politico” and apparently doesn’t show the photos in the summary, only the shortcode [fbphoto id=x]. It works fine when the post is clicked on, just not in the post feeds. Is there a way to make this work?

Here’s the site in question: https://www.haineforsenate.com

Thank you for any help you can provide!
