MS Word figure numbers are wrong

I'm working on a Word 2010 document (editing in Word 2013 with compatibility turned on). The document has captions on figures with chapter (set) and number on them, such as "Figure 3-1" for chapter 3, figure 1. However, there are figures that are missing from the References > Cross Reference > Figures and from the Table of Figures.

So Word goes from "Figure 3-1" to "Figure 3-3". The figure is there on the page but Word doesn't recognize it. Removing and adding the caption doesn't help either. This is driving me nuts! This is a large document (120 pages), so no small feat to recreate the figure captions. Any repair tool for this nightmare? Thanks.

The cause of this perplexing issue is explained here: http://shaunakelly.com/word/sharing/howtrackchangesworks.html#OtherIssuesWithTrackChanges

Simply put, this is normal behavior. When Track Changes is enabled, figure numbers can get out of sync. They'll get back to normal when the changes are accepted/rejected and Track Changes disabled.
