Hey Dlrgirl, in the latest technical release, Category Exhibition has been deactivated for categories with more than 2000 pages, which is why you don't see that option anymore on the Disney characters category page. The blue design on names is because someone added code into the Wikia.css that changes the design of category galleries on standard Category pages. Since the character category pages are technically subcategories and possess less than 2000 pages, they have Category Exhibition turned on and the code is not affecting those pages.

You can find the code on Mediawiki:Wikia.css and the section starts with /* Category Tweaks */, but if you want all the category pages to look the same, you can just deactivate the Category Exhibition feature in Wikia Labs.
