User blog:Kira4real/Braces appearing above templates

When I edit the Manga Chapter pages and insert the templates, I always seem to end up with having two braces “}}” appear right above the template on each page [See image below].

Can anyone explain to me why those braces are appearing on each page above the templates?

I am finding them a bit annoying and I want to get rid of them but I can’t figure out how. Can anyone explain how to me, or at least just tell me why they think the braces are appearing?
