Blog Excerpts Not Pulling Correctly

My site has started displaying my blog excerpts incorrectly. The first six blog posts pull correctly, but then all the following excerpts show only the title, category, social share buttons, and date posted. The excerpt, feature image, and “leave a reply” link are all missing, and the formatting is goofy.

By using web developed in Safari, I can see that the <div class> and <footer class> are missing from these posts and not the others, but I have no idea what’s created this issue. I didn’t make any changes/updates before the issue began occurring, so I’m struggling to know what caused this.

All themes/WP/plugins are up to date, and I’ve tried disabling all plugins to see if that was contributing – to no avail. Please help!
