Category:Pages using duplicate arguments in template calls

From Tardis Wiki, the free Doctor Who reference

Pages are automatically added to this category if a template on them includes multiple arguments for the same parameter. This results in the latest argument listed replacing any others. This includes transcluded templates such as and navboxes, which may result in every page it is on being placed in this category, even if the template, and not a separate problem on the page itself, is at fault.

This is a hidden category.[[edit source]]

Users cannot see it by default. In order to see it on pages where it has been placed, users must click an option in Special:Preferences.

In general, categories should not be hidden. However, in the case of categories which are created solely for use with advanced coding functions like DPL or SMW, then it can be useful to hide them.
