When you're editing the page, look on the right and you'll see a list of categories. Put your cursor over the one you want to change or delete, and you'll see a pencil and trash can symbols.

P.S since it was change (before u used to just backspace to remove it) i had to ask wonderbuono about cuz i didn't know how to do it to so hope that help and let me know if there's anything i can be a help of :)
