Two Home Buttons

Hey

I just downloaded the Orizon-Theme WP and installed it.
Unfortunately there are 2 Home Buttons.
I don’t know whether I’m just stupid but can’t find how there could be 2 Home Buttons integrated. No categories or pages with the name Home. 
(Complete New WordPress)
How do I fix it?

View Source from page dont know if it helps:

<div id="menu_wrapper">







  <div id="menu_left"></div>



  <ul id="menu">



    <li><a href="http://dtkd.decimo.net">Home</a></li>



    <div class="menu"><ul><li class="current_page_item"><a href="http://dtkd.decimo.net/" title="Home">Home</a></li><li class="page_item page-item-2"><a href="http://dtkd.decimo.net/?page_id=2">Beispiel-Seite</a></li></ul></div>



  </ul>



  <a style="width: 940px;" href="#" id="pull">Menu</a>



  <div id="menu_right"></div>



  <div class="clear"></div>



</div>

THanks a lot
