I checked this out on a couple of sites and I think Miss Kitty is right, Bessie. I think you meant that all the
cylinder values were negative, which is what you put in your title. I think you probably typed "sphere" when you meant "cylinder," right?
As for why the cylinder values were negative, I really can't help you with that. Sorry.
