New MultiBody Explode Bug(s) ???

Hoping someone here can verify some issues I've been having regarding the (new in SW2012) Explode MultiBody functionality. Attached is a simple sheetmetal part that comprises several different bodies. The first issue relates to the auto-spacing of exploded bodies. It seems that once the step has been applied, there is no way to go back and modify distances. Inconsitent behaviour in this area leaves no option but to manually place all bodies by eye.

The second issue related to one of the features (the cylindrical tube) not returning to it's as modelled state after deleting it from a step it was previously applied to. Our local VAR has passed the file over to SW who was able to delete the Move/Copy feature seen in the Cut List. Unfortunately, neith my VAR nor myself can delete this feature ourselves.

Just wondering if anyone else here has encountered similar problems with this feature yet.
