Thread:Project:Support desk/Unused category "ghost" page

When I go to Special:UnusedCategories it tells me I have an unused category called All Kings & Queens. When I click on the link to the category page it then tells me this page has been deleted. It also tells me that the page contains no pages or media which makes sense as I have no pages that link to it. To make things trickier, the page displays that it is called Category:All Kings, leaving off the rest of the name. If I manually type in the URL as Category:All Kings, it brings me to the same page as the supposed link to Category:All Kings & Queens.

How do I delete a page that isn't there?
