Dear Xara...

Add an internal Contour to a Shape.
Clone it.
Soft-group both Contour Groups.

Bug - you now cannot remove the Soft-group.

You can remove the soft-grouping by soft-grouping a further non-contoured shape and then removing this soft-group.

You get the same snarl-up if you soft-group a single contoured shape.

You have the same mis-behaviour in XDXv17.1 and v18.0 so an early fix will be appreciated.
