[Plugin: Just Custom Fields] Duplicate images with just_custom_image

For some reason when I use just_custom_image in my page template, it prints two images.

Here’s the code below:

$args = array( 'numberposts' => 3, 'order'=> 'DESC', 'orderby' => 'post_date', 'category' => 258);
$postslist = get_posts( $args );
foreach ($postslist as $post) :  setup_postdata($post); ?>
  <div class="span2">
    <a href="<?php echo get_post_meta($post->ID, 'award-link', true); ?>">
      <?php echo just_custom_image($post->ID, 'award-image'); ?>
    </a>
  </div>
<?php endforeach; ?>

So this prints two img tags with uploaded image from the ‘award-image’ Custom Field.

Any idea why?
