As designed, the Category page URL is an Auto Generated URL following the format, Career_site_URL/brand(if there is)/Categorypagename/CategorypageID. Aside from the brand, which is available on the URL and is not if the category page is created on the main brand, other parts of the URL cannot be removed or updated manually. If the customer wants to have the ability to modify or update the URL manually, the customer can submit an enhancement request for the feature.
