Changing margins adds a couple hundred unwanted pages
I'm a beginner, but used to work in PageMaker years ago, so I didn't think this would be hard. Laying out my book has mostly been a breeze, but I need to change the margins and when I do so, somehow my first page ends up on page 220 or so. I've been messing around with this all day, removing page breaks, changing the styles for everything, Googling about adjust layout. I've tried changing the margins in the master pages, in all the pages by selecting the pages, in the main doc...every which way.
But nobody else seems to have this exact issue.
Any thoughts? Thank you.
