Post style not working

I’m trying to use this plugin to create a news page.
My repeater template is simply this, because I just want the content of the posts:
<?php the_content(); ?>

The problem is that the style for the posts seems to not load. The first post with the green background is the kind of style they should have. Also, if I load a post that is already on the page, the styling for that one works, which makes it seem like there is something that is done when the page loads, and not when I click the button.

The page I need help with: [log in to see the link]
