Wordpress getID add active class - wordpress

Question

i have a Wordpress page called Jobs (https://www.bap.cc/jobs/).
There i want to display two different posttypes (Jobs & Jobsangbote).
Everything works well, except the active function in my php. The first block “Wir suchen“ is okay, “Wir bieten“ active function doesn't work. Don't know why...
<?php
get_header(); ?>
<div class="overflow-y ios blur"><article class="article barba- container"><div id="agenturtext" class="text overflow firefox">
<?php
// Start the loop.
while ( have_posts() ) : the_post();
echo '<header>';
the_title('<h1 id="agenturheader">','</h1>');
echo '</header>';
the_content();
// Include the page content template.
//get_template_part( 'content', 'page' );
// End the loop.
endwhile;
?>
