It sounds like you have a cosmetic issue--not a functional problem. Unless the camera won't fold and close or the bellows intrude into the image path, there's little reason to buy a new bellows. There are a number of fine bellows makers, so if and when you need new bellows, you'll be able to get them. A small amount of misfolding isn't likely to cause holes, but if you want to try correcting the issue, you could remove them, fold them correctly, and keep them folded and compressed for an extended period. Honestly, if your camera folds without an issue, I'd just forget about it.
