I'm probably doing something wrong, but I can't figure it out.

I have it set up as such:
 * Craig of the Creek
 * Category:Seasons|Seasons
 * Category:Episodes|Episodes
 * Category:(Characters)|Characters
 * Category:(Main_Characters)|Main
 * Craig
 * Kelsey
 * J.P.
 * Category:(Supporting_Characters)|Supporting

On this wiki: https://craig-of-the-creek.wikia.com/wiki/Craig_of_The_Creek_Wiki

Some of the categories that currently exist lead to dead ends saying they don't however. Characters, Main Characters, and Supporting Characters do have categories already but the links aren't working. Help?
