Your edit has triggered an automated filter because it looks like you're trying to use a stub category directly. Please note that the way we use stub categories is using stub tags - please see here for instructions. In general, the stub tag for a specific stub category can be found in the instrunctions in the category page, before the subcategories and pages. Please also note that using the stub template is enough to include the page in the stub category - there is no need to add the category in manually.
If you are not attempting to categorize a stub in a stub category, please report this.
