file info vs file properties

[#1]

… the sort of thing you notice when you have to regenerate a book six times in the same day because of last-minute input: the File info I have tidily included in my .book is not being carried over to the File properties in the output .pdf

Any ideas on getting these two instances of the same content into lockstep?

How do you create the PDF? > File > Save as PDF? Or > File > Print Book?

If  > File > Print Book, is "Generate Acrobat Data" activated in the Print Book dialog?

"Save as .pdf" – and yesterday, it gave the correct info in one book out of three … :-}
