When I change the width and height the size automatically reverts back to a size that is some 20 pixels off. I need the artboards to be precisely 2160x1920 which is the size they were when created, but somehow they change to different sizes like 2180x1916. When I try to update the size in the field, as soon as I click off the field the dimension goes right back to the old, incorrect dimension. I cannot save it out to the correct dimension. I can drag the size of the artboard with the artboard tool, but that is impossible to get to the correct dimension since it jumps from 1919.67 height to 1921.xx I have about 20 artboards in a single document
