I've been having a problem getting this part of my wikia to work:

Main Characters I thought if I tagged the pages I wanted to appear here with the Main Character category, it would display them as thumbnails, as I have seen on many other wikias. But it has not done this, on either this page or the two other similar pages.

Does anyone know what steps I missed to get these pages to display content as intended?
