Element is triggering for previous Author and Current Author

Hi there,

I use the Hook Element to display and author box at the bottom of a page. The problem is, when I change author, it shows both the last and the current author at the bottom. It (for some reason) also shows the featured image at the bottom.

Can you find the issue?

Here's the author box code:

<div class="author-box">
	<?php 
	
	global $post;
	
	?>
	
	<div class="avatar"><?php echo get_avatar( get_the_author_meta( 'ID' )); ?></div>
 
        <h5 class="author-title"><?php printf( esc_attr__( 'Om %s', 'the author' ), get_the_author_meta( 'display_name') );?></h5>
	
				<div class="author-summary">
	
        <p class="author-description"><?php echo wp_kses( get_the_author_meta( 'description' ), null ); ?></p>
 
    </div>
 
</div>

And here's the URL: https://techeksperten.dk/tests/kaffemaskine-med-kvaern/

It shows both "Techeksperten" and "Admin" box. It's shown as a separate post at the bottom, which is quite confusing.
