Category:Pages using duplicate arguments in template calls

This category contains pages with template calls that pass the same argument (parameter value) more than once, such as  and. When the same parameter is given a value more than once in a template, only the final value of that parameter is used to display the template. See Help:Duplicate parameters for more details and tips. Other venues to find duplicates: For a list of MediaWiki-populated tracking categories, see Special:TrackingCategories.
