Reply To: Margins mystery, headers reappear

Do the header boxes touch each other on the master pages? (i.e., overlapping to margins/gutters). Are they grouped across the spread?

I’ve had similar problems, especially if there is an inside bleed.

In the current job I’m working on, I had to nudge the right-hand box over .5 points from the inside gutter.

I know your problem is left-hand pages, but maybe it’s something similar.
