XFDoc Word text size changing upon processing

We have XFDocs set up to open in Word.  The text is Times New Roman, size 12.  Some, not all, of the text shrinks to size 10 when the document is processed.  I noticed that the text that resizes has a "Normal" style.  The text that doesn't resize doesn't seem to have a style at all.  If I copy the format of the non-styled text and paste it over the Normal style text, it won't resize when processed.

Does anyone know more about this?  Is there a way to prevent the resizing or set what "Normal" should process as in OneStream?

Thank you.
