Hide EventCalendar category from loop

Hi

I’m trying to hide posts (events in The Event Calendar plugin) from my loop. I think an easy way would be to hide the category that they belong to, but how?
I seems like these event categories are separated from the core WP categories.
This is my loop:

<?php if ( have_posts() ) : ?>
	<?php while ( have_posts() ) : the_post(); ?>
		<?php get_template_part( 'content', get_post_format() ); ?>
	<?php endwhile; ?>
	<?php vantage_content_nav( 'nav-below' ); ?>
<?php else : ?>
