In reading another thread on this, I now recall that the problem is with using the Outline Style rather than the Book/Continuous style. The Book/Continuous style allows for a prologue; however, this style is incompatible with a multi-novel series contained within one AT project. Thus, those of us who are writing a multi-novel series use the Outline Style. But with the Outline Style, we get the chapter-count problem raised in this thread if we wish to include a prologue in the narrative.
As does @DuchGB, I prefer the Outline style anyway. I do, though, see why Grzegorz would welcome the ability to make the prologue chapter “0” or, per my suggestion, to exclude it from the chapter count.
As long as we’re discussing this, I’ll add my two cents on the Book/Continuous style: It makes me spill my coffee because it increments the number of each scene from the first scene of the novel, rather than from the first scene of the chapter. Thus, we get the unhelpful “Chapter 4, Scene 45;” as there are only three scenes in that chapter, it should be, to my mind, “Chapter 4, Scene 3.”
