I have about a 40 page booklet layout. For some reason, most of my right side pages are several inches higher than pages on the left. Not all of them, just most. This doesnt seem to interfere with anything or making the PDF's but its just a little screwy. What could be causing this and how do I fix?
Switch to Page Tool (Shift+P). Holding ctrl/cmd select your pages in question, in Pages palette. Please see enclosed screenshot.
Ensure you have Layout Adjustment Off and Objects Move with Page - On.
Notice 10 mm value in my Y box - thats why pages are shifted. Simply enter values you need (it must come to zero, if you follow screenshot) to align your pages.
Hope that helps.
I'd run in to a same situation as yours at first time, and I also got no ideas how to fix. This reminded me of the pageview control, and I know to be more familiar with the thing, this kind of question can be easily solved. What aboved said was just that I want to say.
