Having difficulty with a nested query using ACF

Hi there,
I’m working on a portfolio page with a modal pop up. The portfolio part of the pages is one query in a carousel with a set of posts pulled by meta key (featured item checkbox true), and then the modal includes yet another carousel of all images inside the individual posts displaying in the main portfolio carousel. I may not be explaining this well.

Anyhow, the problem I’m having is that only the first modal has the associated image/s. All the others are not pulling images, even though they all have at least one. Here’s my code. Any help that can be afforded will be hugely appreciated!

<?php 	$args = array(
		'post_type' => 'pixieportfolio',
		'post_status' => 'publish',
		'orderby' => 'menu_order',
		'meta_query'	=> array(
			array(
				'key'	  	=> 'featured_portfolio_item',
				'value'	  	=> '1',
				'compare' 	=> '=',
			)
		),
		'meta_key' => '_thumbnail_id',
		'posts_per_page' => 999
	);

	$query = new WP_Query( $args );
	$count = 0;

// Carousel // ?>
<!--<div class="more-button">
	<a href="/portfolio-all/">More Projects</a>
</div>-->

<div id="featuredCarousel" class="carousel slide" data-ride="carousel" data-pause="hover">

	<!-- Indicators -->

            <li <?php if($count == 0){ echo 'class="active"';} ?> data-target="#featuredCarousel" data-slide-to="<?php echo $count++; ?>">

          <?php endwhile;  wp_reset_postdata(); ?>

	<div class="carousel-inner" role="listbox">

		<?php $count = 0;

			while ($query->have_posts()) : $query->the_post();

			$url = $thumb['0'];
