Perhaps a description of how this is used / how it is supposed to be used? What you mean by "broken"? Plus a 2nd upload with a good, working example?

Explored your upload a little. The top level grp shape has Shape Data definitions. If each of these is addressed, everything seems to fill in, textually, as shown in "good" shape. What is different is the line outline of the textboxes. Textbox, btw, is just a regular shape with linewidth=0.
Other than that, what's broken?
