My comments template shoves content away when updating a comment

I have a problem with comments in the WordPress theme I’m building. As of now, I can comment just fine, but whenever I do (press “reply”, “edit comment”, press the date, really anything that involves updating a comment), my header and site content dissapears and I’m stuck with the comment i interacted with at the top of the site/content-wrapper and everything below it (sidebar, footer, other comments that’s below that one).

Here’s a screenshot of what happens:

And here’s my comments.php:

<?php
/**
 *
 *  Comments themplate - Adapted Version of Kubrick's
 *
 *  There are 2 distinct sections after the protection area ::
 *  Display Comments is a loop surrounding the wp_list_comments() function
 *  The Form/Login section uses comment_form() to do everything
 *  ( Finally the RSS link is at the end of the page )
 *
 *  */

// ##########  Do not delete these lines
if (isset($_SERVER['SCRIPT_FILENAME']) && 'comments.php' == basename($_SERVER['SCRIPT_FILENAME'])){
die ('Ikke last denne siden direkte. Takk!'); }
if ( post_password_required() ) { ?>
<p class="nocomments"><?php _e('Denne posten er passordbeskyttet. Skriv inn passordet for ? vise kommentarene.', 'kubrick'); ?></p>
<?php
return; }
// ##########  End do not delete section

// Display Comments Section
if ( have_comments() ) : ?>
<h3 id="comments"><?php comments_number('Ingen kommentarer', 'én kommentar', '% kommentarer');?> <?php printf('til “%s”', the_title('', '', false)); ?></h3>
    <div class="navigation">
        <div class="alignleft"><?php previous_comments_link() ?></div>
        <div class="alignright"><?php next_comments_link() ?></div>
    </div>
<ol class="commentlist">
 <?php
 wp_list_comments(array(
  // see https://codex.www.ads-software.com/Function_Reference/wp_list_comments
  // 'login_text'        => 'Login to reply',
  // 'callback'          => null,
  // 'end-callback'      => null,

  ));
  ?>
</ol>
    <div class="navigation">
        <div class="alignleft"><?php previous_comments_link() ?></div>
        <div class="alignright"><?php next_comments_link() ?></div>
    </div>
<?php
if ( ! comments_open() ) : // There are comments but comments are now closed
    echo"<p class='nocomments'>Kommentarer er stengt.</p>";
endif;

else : // I.E. There are no Comments
if ( comments_open() ) : // Comments are open, but there are none yet
    // echo"<p>Be the first to write a comment.</p>";
else : // comments are closed
    echo"<p class='nocomments'>Kommentarer er stengt.</p>";
endif;
endif;

// Display Form/Login info Section
// the comment_form() function handles this and can be used without any paramaters simply as "comment_form()"
comment_form(array(
  // see codex https://codex.www.ads-software.com/Function_Reference/comment_form for default values
  // tutorial here https://blogaliving.com/wordpress-adding-comment_form-theme/
  'comment_field' => '<p><textarea name="comment" id="comment" cols="58" rows="10" tabindex="4" aria-required="true"></textarea></p>',
  'label_submit' => 'Kommentér',
  'comment_notes_after' => ''
  ));

?>
