Issues with Text Wrapping in PowerPoint Gamma Downloads

I have mentioned this before, but wanted to bring it up again. When downloading a gamma as a powerpoint, some of the text boxes allow the text to wrap naturally, others do not. This means that when I am making fonts consistent in the deck in size, often text will extend outside of the non-text wrapping boxes. This means I need to stop and create a text box from powerpoint and then copy and paste the text. Or, add a hard return. Is there any reason why all text boxes are not text wrapping?
