Почему под админом слайдер-карусель на главной выглядит криво?

<?php                  
                     if (Core::moduleIsActive('informationsystem'))
                        {
                           // Карусель
                           $Informationsystem_Controller_Show = new Informationsystem_Controller_Show(
                              Core_Entity::factory('Informationsystem', 20)
                           );                  

                           $Informationsystem_Controller_Show
                              ->xsl(
                                 Core_Entity::factory('Xsl')->getByName('КарусельНаГлавной')
                              )                              
                              ->limit(3)
                              ->show();
                        }   
                     ?>
