You’re talking about the naming in wp-admin backend?
I didn’t find “Categories” anywhere on your page.

this is my code:
<li id=”menu-item-21″ class=”menu-item menu-item-type-post_type menu-item-object-page menu-item-21″><?php wp_list_categories(‘orderby=id&use_desc_for_title=Our Products&child_of=4’); ?><span class=”sf-sub-indicator”></span>
