Remove category, theme Badjohnny

Hello,
I’m trying to remove the category from showing next to the title, I’ve read on other forums that I have to change the category.php but mine looks completely different from the ones I’ve seen.

Mine looks like this:

<section id=”primary” class=”site-content”>
<div id=”content” role=”main”>

<?php if ( have_posts() ) : ?>
<header class=”archive-header”>
<h2 class=”archive-title”><?php printf( __( ‘Category: %s’, ‘badjohnny’ ), ‘<span>’ . single_cat_title( ”, false ) . ‘</span>’ ); ?></h2>

<?php if ( category_description() ) : // Show an optional category description ?>
<div class=”archive-meta”><?php echo category_description(); ?></div>
<?php endif; ?>
</header><!– .archive-header –>

<?php
/* Start the Loop */
while ( have_posts() ) : the_post();

Does anyone know how to solve this?
Thank you!!
