Shape Text Box problem

I'm having problems when I copy ( clone ) a file across using Aspose.Word which contains Text Boxes in Text Boxes.

I understand that there is an issue with Z-ordering, but any ideas on how to get around this, and when this likely to be corrected

I've attached an example of the word source document.

Each shape has an anchor that is usually displayed to the left of a paragraph in the main text when you click on a shape. Just pull the anchors to be in different paragraphs. This will allow you to keep the textboxes as is, yet escape the Z-order problem.
