User blog:Tormented Sufferer/Deleted MediaWiki pages' links

Hello. I am a bureaucrat of Ōkami Wiki, and I would like to ask about a persisting problem on the site. As it can be seen in the first image of the gallery below, the MediaWiki pages defining badges' name (which is a disabled function), which I deleted myself and they were not restored, still have their links accessible. Furthermore, when these links are accessed, the pages' former content (badges' name) are shown, underneath the deletion log (the second image below), instead of the usual sole log in all other deleted pages. So now I'd like to ask the cause of this bug and how to resolve it. Thank you for reading this post. File:MW badge link.png|The list of deleted pages. Note the deleted MediaWiki pages defining badges' names having their links looking as if they do exist.

 * Note: Even though I use a customized Monobook skin, this bug exists on all skins (site's primary Monobook, Oasis, Vector and CologneBlue).
