Word 2013 vs Word 2010 formatting issue?

[rhoyt]

I have 20 chapters currently in .docx format, created in Word 2010. We have someone converting the 1 column chapters into 2 columns and saving them as .docx. In spite of what we thought was 100% compatibility, they are not. They look ok to her but when we view using Word 2010 the right column is always higher and there are gaps in the text we can see but she can not.



The attached .png file is a screen shot. Is this a page setup issue, rather than a version issue? Thanks for any help....Bob
