title: Drupal - menu items linking to the same node do not display all children
body: <p>i have got a menu structure like this:</p>
  
  <p>-menu item level 1</p>
  
  <p>--menu item level 2</p>
  
  <p>---menu item level 3</p>
  
  <p>all items are linking to the same node. now, if i visit the node only the first two items are displayed. what i found out is: when i change the link of the first level menu item to something else, all level get displayed right.</p>
  
  <p>menu modules i use:</p>
  
  <ul>
  <li><p>Menu block</p></li>
  <li><p>Menu Settings per Content Type</p></li>
  <li><p>Menu Trails</p></li>
  <li><p>Administration menu</p></li>
  <li><p>Auto Menu Title</p></li>
  <li><p>Hierarchical Select</p></li>
  </ul>
  
  <p>any ideas?</p>
  
  <p>thanks</p>
