WordPress inserts opening <div> tag twice.

Hi,

WordPress is putting an extra opening <div> tag into my pages. Please review the code below, and not the double occurrence of <post-content>

This is my loop:

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

	<div class="post" id="post-<?php the_ID(); ?>">
    	<div class="post-headin"><h2><?php the_title(); ?></h2></div>
    	<div class="post-content">
      		<?php the_content(); ?>
        </div>
                  <p class="postmetadata">
            <?php edit_post_link('Edit', ' | ', ''); ?>
            </p>

	</div>

<?php endwhile; else: ?>
<p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
<?php endif; ?>

This is the output

<div class="post" id="post-14">
    	<div class="post-headin"><h2>Experience + Reputation</h2></div>
    	<div class="post-content">

         <div class="post-content">
<p>Yada yada yada</p>
         </div>

        </div>
        <p class="postmetadata">
             | <a class="post-edit-link" href="https://www.islandscapetransformations.com.au/wp-admin/post.php?action=edit&post=14" title="Edit post">Edit</a>            </p>

	</div>
