Wiki page in question:

I was trying to add "Media icons" to my pages to differentiate the different versions of the characters but whenever I try to add them to the page, it messes up not only the table of contents but the entire page format and text as a whole.

I have no idea what's causing this issue, so I don't know if it was the template data or my common.css that caused it, either way I have no idea how to fix it. If I could get some help on this, that would be great!
