Created Competition not producing Champions NEED FIX

I have created a new competition in the editor. It works fine, all the teams qualify as they are supposed to, all the matches take place on the dates they're supposed too. However, when the competitions finishes, like other competitions, have holders and the team that win it is noted on their pages and on the competition page, this doesn't happen with this tournament. Why is that? Is there something that can be done to alter this?
