How I got this result:
1. Started with a Standard Base Cabinet
2. Went into the Door/Drawer Editor
3. Selected both existing doors, to make changes to the Insets and Overlaps
4. Changed the Door Inset value first, and clicked OK - no problem
5. Changed the overlap values for the existing doors ===>> BAM!!! Doors reacted badly, as shown in the image below.
I can reproduce this, so it does seem to be a bug. This does NOT happen when removing the existing doors and adding new ones - it happens ONLY if I change the settings of the existing cabinet doors.

P.S.: I think this is all Dan's fault
