Text block corruption using Fade animation by Paragraph

I have a large multi-scene module where slides that contain a block of text are getting corrupted. I believe this is only happening with text blocks that have a fade animation applied using the "by paragraph" option. The text block is within the slide but the text is extended to the right, way outside the slide and there appears to be no way to recover the text back in place without recreating the text block. I am not sure if changes to my Master Slides are causing this or not. A sample SL file illustrating the problem is attached.
