just go to a comic, do what you do to type in a creator, type in the newest creator as indicated on the side, and then click their name when they pop-up. instead of showing up in the box indicated "colorist" or whatever, there will be a long line of code ending in the creators name. when you hit submit with that code highlighted, it doesn't add the creator.
this glitch fixes itself after a while though somehow.
