I recently imported a stub template from the Ace Attorney Wiki and set its type to sub-template like the Life is Strange Wiki to ensure it works on mobile. However, when I add the template to a page, the template's image shows up as an added image on the Recent Wiki Activity page and often appears as the page's preview image on category thumbnails, which never happens on either of the wikis I mentioned. How can I fix this?
