ACF Repeater field returns null value - php

Question

I am trying to include a repeater field in a custom taxonomy template but it keeps returning No Posts to display. I know there are posts to display so I am baffled.
I have tried adding in wp_reset_postdata() but that didn't do anything, I am getting no errors.
Here is the repeater in question:
<?php if( have_rows('feature_repeater') ): ?>
<div class="related-posts">
<h2>You May Also Like...</h2>
<div>
<?php while( have_rows('feature_repeater') ): the_row();
// vars
$image = get_sub_field('collection_image');
$content = get_sub_field('collection_title');
$link = get_sub_field('collection_link');
?>
<div>
<?php if( $link ): ?>
<a href="<?php echo $link; ?>">
<?php endif; ?>
<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt'] ?>" />
<?php if( $link ): ?>
</a>
<?php endif; ?>
<?php echo $content; ?>
</div>
<?php endwhile; ?>
</div>
</div>
<?php else : ?>
No Posts to Display
<?php endif; ?>
and here is my template:
<?php
/**
* Template used for single posts and other post-types
* that don't have a specific template.
*
* #package Avada
* #subpackage Templates
*/
// Do not allow directly accessing this file.
if ( ! defined( 'ABSPATH' ) ) {
exit( 'Direct script access denied.' );
}
?>
<?php get_header(); ?>
