Problems with Animation Handling

Dear Xara...

I was trying to create a button with an overlay of colour atop some text so the text is shown through a Multiply Transparency.

Bug#005a - Smart Duplication fails when both overlay and text are selected
I do not understand why a Rectangle and a Text Column cannot be Smart Duplicated when one covers the other (Rectangle over Text or Text over Rectangle).
When there is a hint of a spill-over, it works.
Bug#005b - Overlay becomes an image
When a Multiply Transparency is applied, the overlay is forced into being rendered as an image.

The other Bugs relate to the addition or an Animation.
Bug#006 - overlay disappears when Click Animation is applied
Bug#007 - overlay becomes an image combined with the under text with if a Mouse-over or Reveal Animation is added

Here is my test file: Attachment 129824
