Hello. I've created an infobox, but there is a problem. My wiki is about professional wrestling and you can see here that the infobox of the professional wrestler is blue on top (where the wrestler's name is). The same thing happens in this article too, but the blue box is bigger.

I want to get rid of the blue boxes (the small ones and the bigger ones). Can someone help me please?
