files in book which end up with 2 pages

[Theresa de Valence]

Frame 8
Book has 10+ different master pages, but they are mostly simple changes: 
1 column page, 2 column page, different footers left & right, sometimes 
a running header, sometimes not.

In Book, Pagination is not available.
 From the Book file, for the first file in the book, pagination is set 
to Double-sided, 1st Page Right, Delete empty pages before saving & 
printing, Every other file is set to: Double-sided, 1st Page side: read 
from file, delete empty pages.

For each file, separately from book, Format/Page Layout/Pagination is 
set to Double-sided, 1st page Right (no option to follow from prior file)

I have two problems:
1. The second file in the book has one page. I have manually set that 
page to Doublesided, 1st Page right, Delete Empty pages BUT every time I 
generate the book, it ends up with 2 pages.

2. The second is that I have different L and R master page formats and 
whether the first page is L or R depends upon what page # it is. I 
thought I was setting these inputs correctly, but maybe not.

Any help?

Thanks,
Theresa
