An odd page number has to be on the right side of a spread in LTR languages, as it is standard. For empty pages you have to insert a blank page.
I don't understand your screenshots, why is the margin guide in the spine not showing a space to the spine ans it should?
Does that blank page then have to print? Also, I'm afraid I don't understand your question.
Does that blank page then have to print?
I notice that you have page shuffling turned off for spread i-ii (which was required to force the pages into the wrong sides). If you want to have the content of page i backed up to page A, you can either remove the section and change Page A to start at i, then add a blank page after page iv, or you can simply start that section with page ii instead of i (and still add the blank page at the end of the section). If page i can be on the right, and the back of page A can be blank, add the blank page after A and re-enable shuffling for i-ii.
Willi's question about the margin was because your second screen shot shows what looks like a two-page spread with no inside margin (though there is a rule guide either obscuring the page edge at the gutter or you have set up a single page with two "pages" on it and that would be a disaster.
In a sort of round about way, I figured out that I could do what I wanted to do using the Pages fly-out menu, I just had to do some of the operations twice. For example, if I started a new section on a left hand page and chose "automatic numbering" and told it to start at 1, it would, in fact, start at two. But then if I went back and changed it back to 1, it would stay at 1.
