I did ticket 68268 on this:
I did a print of a letter size page for testing. And it wouldn't center, so i looked on other modes and saw this in "Profile Mode"
I haven't looked much more yet for the problem, might be my drawing. I'm assumming the dashed line on the profile page is "0" of that floor,
Anyway i'm going to look at it more so to fix. but thought i would throw it out there in case the patch did something.
