I have a preset layout on Indesign CC V. 9.1 with a document that has 5 chapters, A front matter, back matter, endnotes and appendices. I have the layout as a facing page--needed for odd and even formats. Everytime, I add an extra page so that way my next chapter could start on the right side(front of the book/report), the chapters after that shift the textbox frame out and shuffle their top margins. The left page goes from 1.5inch to 2inch of a margin and the right side goes from 10inch to 10.5inch and I have to move it all back.
My bleed and slugs are all the same at .125 in, Facing pages are on. I don't understand why this is happening and how can I change this so that way it doesn't shuffle?
