Help reset figure numbers in large book (to continue from previous chapter)

Good morning: I am helping a colleague with a large manual that was set up in FrameMaker a long time ago (i.e., may have strange formats that were never removed, but difficult to find). My problem: the last chapter of this book does have the page numbers set up correctly (i.e., p one of the chapter is 279), but the figure numbers do not (they start at 1)! It's an auto format,as I tried to update just the number (do it manually out of desperation).

I have been trying to manage the figure numbers using the numbering dialog in the book, or through paragraph format updates, or variables ... I cannot figure that out! Unfortunately, I cannot share the book with you. It's medical device proprietary. Thank you. Deanne Levander

If screen shots of specific settings, etc. (numbering dialog, paragraph designer, etc.) would be helpful, let me know.
