Specturm theme menu order is reversed

With the Spectrum theme
https://www.ads-software.com/extend/themes/spectrum
the menu at the top of the page displays in reverse order, and I’d like the pages to display in the correct order. I have set the page order for each page, 0-5, and they display correctly in the footer menu.

The div in header.php looks like this:

<div class="pageList">
     <ul>
          <?php wp_list_pages('title_li=&depth=1'); ?>
     </ul>
</div>

The client source looks like this:

<div class="pageList">
  <ul>
     <li class="page_item page-item-16"><a href="https://example.com/" title="Intro">Intro</a></li>
     <li class="page_item page-item-25"><a href="https://example.com/who/" title="Who We Are">Who We Are</a></li>
     <li class="page_item page-item-8"><a href="https://example.com/resources/" title="Resources">Resources</a></li>
     <li class="page_item page-item-10 current_page_item"><a href="https://example.com/projects/" title="Projects">Projects</a></li>
     <li class="page_item page-item-12"><a href="https://example.com/blog/" title="Blog">Blog</a></li>
     <li class="page_item page-item-14"><a href="https://example.com/membership/" title="Membership">Membership</a></li>
  </ul>
</div>
