PageBuilder messes up get_the_excerpt() function

I realize you may need to see more code to believe me, here is the full template.

<?php
$current_post_id = get_the_ID();
$term = get_term($term_id);
?>
<aside class="in-this-taxonomy">
	<p class="ui-title"><?php echo strtoupper($term->taxonomy) ?>
	<h1><a href="<?php echo get_term_link($term) ?>"><?php echo $term->name  ?></a></h1>
<?php if($title_image){
    $img_url= category_image_src( array('size' => 'vignette-standard-carree'  ,'term_id'=>$term_id) , false );
    ?>
    <img src="<?= $img_url?>" alt="<?php echo esc_attr($term->name)  ?>" >
    <?
}
// Process the post selector pseudo query.
$args = array(
	'tax_query' => array(
		array(
			'taxonomy' => $term->taxonomy,
			'terms'    => $term_id,
		),
	),
);
$query = new WP_Query( $args );
global $post;
if($query->have_posts()) {
	$total = $query->post_count;
?>
<ol style="counter-reset:taxonomie <?php echo ($total+1) ?>;" class="taxonomy-link-list">
<?php
	// Loop through the posts and do something with them.
	while($query->have_posts()) : $query->the_post();
	setup_postdata();
	$selected = ($current_post_id == get_the_ID()) ? 'class="selected"':'';
?>
	<li <?= $selected ?>><a href="<?php the_permalink(); ?>" title="<?php echo esc_attr( '' ); ?>" class="popup">
		<?php
	echo replace_br_by_space(get_the_title());
        // uncomment this breaks the page.
	//the_excerpt();
?>
		</a></li>
	<?php
	endwhile;
	wp_reset_postdata();
}
?>
</ol>
</aside>
