OK I understand what is unique.
But I still think that the number in "Figure 16." should be automatically generated.
Or we can remove this Figure/Table list at the bottom of the index.

OK, it was a misunderstanding. I agree the cross references are useful.
I'm speaking only about the Figure/Table list at the bottom of the index.
