I have an annoying problem: I can't get the center mark to be in the center of a slot! I had a perfect drawing, now, after a minor dimension change, all my sections views don't display the center mark in the center. Please see image below.

No matter what I select, the center mark snaps off-center. I tried a few things like changing the display to shaded with edges, moving my section line to force a view update, and even tried different slot center marks to no avail.

Thanks for your help,

Ren
