Fill tool causing seemingly random sections to be painted

I was following everything smoothly and filling in the metal pieces. but when painting this one piece in particular it caused a small area of the image to get painted as well, which streaks across multiple UV's. Is there any reason this might be happening?

before painting

after painting (you can see the problem emerge in the top center)
