Extra output in custom wp_list_pages

Hi —

In a menu, I want to display only the current page + ancestors + child.

I’m using this:

<?php
//if the post has a parent
if($post->post_parent){
  //collect ancestor pages
  $relations = get_post_ancestors($post->ID);
  //get child pages
  $result = $wpdb->get_results( "SELECT ID FROM wp_posts WHERE post_parent = $post->ID AND post_type='page'" );
  if ($result){
    foreach($result as $pageID){
      array_push($relations, $pageID->ID);
    }
  }
  //add current post to pages
  array_push($relations, $post->ID);
  //get comma delimited list of children and parents and self
  $relations_string = implode(",",$relations);
  //use include to list only the collected pages.
  $sidelinks = wp_list_pages("title_li=&echo=0&include=".$relations_string);
}else{
  // display only main level and children
  $sidelinks = wp_list_pages("title_li=&echo=0&depth=1&child_of=".$post->ID);
}

if ($sidelinks) { ?>
<h2><?php the_title() ;?></h2>
  <ul>
    <?php echo $sidelinks; ?>
  </ul>
<?php } ?>

The problem is that I get the current page title (“Test menu” here, parent page is “TEST”) printed within <h2> tags (and without closing /ul tag) breaking the menu as seen here:

HTML source code output :

<li><a href="#">Pages</a>

        <ul>
        	<h2>Test menu</h2>
  <ul>
    <li class="page_item page-item-116 current_page_ancestor current_page_parent"><a href="https://www.mysite.com/films/test-3/" title="TEST">TEST</a>
<ul>
	<li class="page_item page-item-122 current_page_item"><a href="https://www.mysite.com/films/test-3/test-menu/" title="Test menu">Test menu</a></li>
</ul>
</li>
  </ul>
        </ul>

      </li>

I’m using “Fullscreen theme” on 2.9.2

Where should I look up to fix this?

TIA.
