Breadcrumb Shop link twice (Woocommerce)

AH Sorry guys.. I tried the first Solution…

This as working for me

   if(!function_exists('avia_modify_event_breadcrumb'))
{
    function avia_modify_event_breadcrumb($trail)
    {
        foreach($trail as $key => $data)
        {
            if(strpos($data,'href="http://link your site.de/shop-produkte-uebersicht/"') !== false) unset($trail[$key]);
        }
        return $trail;
    }
     add_filter('avia_breadcrumbs_trail','avia_modify_event_breadcrumb');
}
