Joker (Harley Quinn TV Series)

So, I just edited the Joker from Harley Quinn TV Series' page, but I realized there is something off about it. It is like there are... full paragraphs in the contents box. I do not know if accidentally caused this, but I have tried everything to fix it, and I cannot fix it for some reason.

Can somebody take a look at it? Because I am not sure what the problem is.
