It looks as though "accessories", 'apparel", and "performance parts" are actually sub-categories, not categories. Do you have a category named "home"? Make "accessories", 'apparel", and "performance parts" categories (move them from where they are to "root") instead of a sub-category of home. This should leave you with "accessories", 'apparel", "performance parts" and "home" (if that is a category) as categories. Then determine that there are no sub-categories of "home" and no products there. Once you do that you should be able to eliminate "home" (try disabling it first, before deleting it).
