Incomplete disambiguation pages are disambiguation pages that also have a disambiguated title (a title with a parenthetical phrase appended). These disambiguated titles are supposed to be unambiguous; if they are still ambiguous, the incomplete disambiguation should redirect to the main disambiguation page or a section of it. See Wikipedia:Disambiguation#Incomplete disambiguation. If no disambiguation page exists for the title, it may simply be moved to the base page name if available, or to a page name using "(disambiguation)" instead of the ambiguous parenthetical phrase. It could also be that the pages are not disambiguation pages at all, but Wikipedia:WikiProject Anthroponymy articles, set index articles, or other list articles. They should have the disambiguation tag removed (and an appropriate tag added, if available), and they might also need to be renamed.
