Add to cart popup in fancybox instead of facebox

Hallo,

i just noticed that if a user uses the add to cart button of the "SHOPS & TRENDS" (news show gk5) modul it appears a different popup than in the demo of storebox.

In my shop the popup source is this:

<div id="fancybox-wrap" style="width: 348px; height: auto; top: 335px; left: 737px; display: block;">
<div id="fancybox-outer">
<div id="fancybox-bg-n" class="fancybox-bg"></div>
<div id="fancybox-bg-ne" class="fancybox-bg"></div>
<div id="fancybox-bg-e" class="fancybox-bg"></div>
<div id="fancybox-bg-se" class="fancybox-bg"></div>
<div id="fancybox-bg-s" class="fancybox-bg"></div>
<div id="fancybox-bg-sw" class="fancybox-bg"></div>
<div id="fancybox-bg-w" class="fancybox-bg"></div>
<div id="fancybox-bg-nw" class="fancybox-bg"></div>
<div id="fancybox-content" style="border-width: 10px; width: 328px; height: auto;">
<div style="width:auto;height:auto;overflow: auto;position:relative;">
<p>Produkt derzeit nicht auf Lager</p>
<a class="continue" href="/bekleidung/spielerbekleidung/hosen">Weiter einkaufen</a>
<div>Produkt derzeit nicht auf Lager</div>
<br style="clear:both">
<h4>Virtue Spire 200 Hopper - weiss/cyan</h4>
</div>
</div>
<a id="fancybox-close" style="display: inline;"></a>
<div id="fancybox-title" style="display: none;"></div>
<a id="fancybox-left" href="javascript:;">
<span id="fancybox-left-ico" class="fancy-ico"></span>
</a>
<a id="fancybox-right" href="javascript:;">
<span id="fancybox-right-ico" class="fancy-ico"></span>
</a>
</div>
</div>

and in the demo its this:

<div id="facebox" style="top: 635px; left: 691px;">
<div class="popup">
<div class="content my-groovy-style">
<div>
<a class="continue" href="/joomla25/storebox/index.php/component/virtuemart/">Continue Shopping</a>
<a class="showcart floatright" href="/joomla25/storebox/index.php/shop/store-frontpage/cart">Show Cart</a>
<div>The product was added to your cart.</div>
<h4>Unique Men´s Jacket was added to your cart.</h4>
</div>
</div>
<a class="close" href="#"></a>
</div>
</div>

Can you please tell me why it is different?

Thanks
Till
