Frontend Top-level category not showing all child categories in sidebar
I have a top-level category with 4 child categories. The top-level category has no products directly associated to it, but each child category has a couple products associated to each. If I browse to the top-level category on the front-end it presents all the products from all the child categories, however, in the sidebar under the heading "category" once expanded it only lists the first child category and none of the others. Why?
