A few templates on our wiki are not being shown in the category they are assigned to. Categories are being assigned through the template /doc pages, using:
<includeonly>[[Category:Template Category|{{PAGENAME}}]]</includeonly><noinclude> [[Category:Template Documentation|{{PAGENAME}}]]</noinclude>
The category appears on the template page, and other templates in the category using the same exact text appear just fine on the category page. The template's /doc page also properly appears in the Template Documentation category.
I have tried purging the category, template, and doc pages. Some of these templates have been around for a while, so it shouldn't be a 'wait for the servers to refresh' situation.
Is this an issue anyone has seen before?
