Page refreshing after clicking load more button

Hi

I’m having some issues with the page refreshing when I click the load more button.
I am using the standard button from the plugin, generated from the shortcode, with no other JS linked to it.

This is happening on my localhost as well as on a staging server.
I am using a custom repeater template, but there isn’t anything crazy code wise involved.

The issue only seems to occur after I have visited the page more than once.
So, visiting the page for the first time in a browser the load more works fine, but if I then revisit the page with a manual refresh or by clicking a different page and returning, the ajax doesn’t seem to work properly. Clicking the button makes the page refresh (and loads the new content).

My repeater code:

<?php if($alm_item == 1 || $alm_item == 7){ ?>
	<a href="<?php the_permalink(); ?>" class="col-xs-12 col-sm-6 col-md-8 tile ajax_tile">
		<div class="tile-image" style="background-image: url('<?php echo get_the_post_thumbnail_url($post->ID, "medium"); ?>');"></div>
		<div class="tile-content">
			<h4><?php echo get_the_title($post->ID); ?></h4>
			<p class="date">Posted on: <?php echo get_the_date(); ?></p>
			<p class="excerpt"><?php echo excerpt(20); ?></p>
		</div>
	</a>
<?php } else { ?>
	<a href="<?php the_permalink(); ?>" class="col-xs-12 col-sm-6 col-md-4 tile ajax_tile square">
    	<div class="tile-image" style="background-image: url('<?php echo get_the_post_thumbnail_url($post->ID, "thumbnail"); ?>');"></div>
		<div class="tile-content">
			<h4><?php echo get_the_title($post->ID); ?></h4>
			<p class="date">Posted on: <?php echo get_the_date(); ?></p>
			<p class="excerpt"><?php echo excerpt(20); ?></p>
		</div>
	</a>
<?php } ?>

I have tested in Chrome, Safari and FireFox. All up to date versions.
