No matter how many times I change the Spread SetUp (whether I do it for Current, Selected, or All), it reverts to this (see attached). I tried selecting Type: Print, Page Preset: Custom, Dimensions 8" x 10" Portrait, but then when I go back to check it, it automatically reverts to what you see. I'm using Sierra on a mid-2012 MBP.
Also, is there any way to change the Document Dimensions once you've opened a project? I can't figure out how to do a bleed on only the external dimensions, not the gutter. Because of that, I just wanted to include it myself in the doc dimensions, but I couldn't figure out how to change them. Thanks.
