Grouping fail with a Mould

Dear Xara...

I have two shapes that are soft-grouped (XDPXv16.1).
If I select one and apply a Mould, the grouping vanishes.
It is retained if it was a normal grouping.

Further if I then try to apply a soft-group to the shape and Mould, all options are greyed out.

Thanks.

Part of mine remains a soft group. Very odd.

Thanks for confirming Egg.

I applied the mould to the soft-group and not just one part of it.
For our examples, if you detach the mould, the soft-group is restored.

None of this should be happening.
