Update Book feature does not show LOF chapter for updating
I am trying to update my front matter/TOC that also contains a List of Tables and a List of Figures. For some reason, the List of Figures chapter is not available in the Update Book dialog.

If you look closely at the LOF chapter in the Book view below, you will see that TOC and LOT chapter icons are dark brown, while the LOF chapter it is a slightly lighter. Does the color difference indicate something is not configured properly in that LOF chapter? How do I fix this so it will update?
