Image Upload records duplicating

I never seen this before.. I have a page with group of 4 photo. The photos open in a lightbox. For some reason when you click on any of the images and the lightbox pops up, it duplicates the first image of the set 3 times.

i checked my code multiple times and have no clue why this is happening:

<?php foreach ($portfolioRecord['photos'] as $index => $upload): ?>
<a href="<?php echo $upload['urlPath'] ?>" data-lightbox="<?php echo htmlencode($portfolioRecord['title']) ?>">
<div class="tabblock">

<div class="tabimage2"  style="background-image:url(<?php echo $upload['urlPath'] ?>)"></div>



</div>
</a>
<?php endforeach ?>
