If your review didn't mention even a word of why a category gets a low score, people can only assume you are okay with the category. Thus the category score will get normalized. Without that, your review will be breaking the review guidelines for being unreasonable. So either score normalized or review deleted. Server owner cannot edit review. If you don't want that, write a review that doesn't go at a different direction with the score given (that means follow the review guideline). You have the option to delete it and write another at the user panel. Since it is you, I really don't think you would mix up the score scale direction.
