Chapter Numbers in Compiled

OK. So. I compiled my novel in Manuscript Format.Thus ends my novel and begins my formatting woes.

My current chapter one header reads Chapter Two: Title. All my other chapters are in numerical order, so I can’t presume all my deleted and reordered chapters have done something (and I’ve deleted and reordered a lot of chapters, I’m a writer, we all know how this goes).

Because I’m a perfectionist, this is driving me absolutely bonkers. Can either tell what I’m doing how to fix it or point me to a good guide to chapter titling metadata that does something similar?

Either would be much appreciated. Still running 1.9 for Windows as I’m looking for my old license number.
