We give you the option to off offset (push the mid-rail down) so all but the reveal (typically 3mm or 1/8") is available for doors below to land on, making the bumper pad position on the doors below less critical.
This offset looks something like this (the left image is with line to 8mm (.315"), the right image is with the option set to centered):
If you prefer this mid-rail be centered as shown in the image to the right, then simply set line 69 to 0mm (0"), and it will stay that way until you change it (KCD updates will not affect settings you change).
