Word template with checkboxes - duplicate checkboxes when completed and saved

This is one of the oddest things I have ever run across.

I have a Word document that I created. It is saved as a template.  In the document are some check boxes, just basic yes and no.  

The template opens as a new document just fine and all items can be completed.  I did notice I have to click on the check boxes once to select them, then again to add the check mark in the appropriate box.  At this point, everything still looks fine.  I complete the document, rename it (must do this, as it just opens as "Document") and save as a Word document with the appropriate name.  

This is where it gets weird.  When I go back and open the saved document (that was created from the template), whatever check boxes were not selected are duplicated.  I.E. if i checked yes in the first check box, the no check box next to it appears twice in the saved document.  If I checked no in the second check box, the yes box in front of it is duplicated.  This happens for all checkboxes in the page.  If I don't select either checkbox, then they appear normal.  It is only if I select one that the unchecked one is duplicated.

I am baffled.  Any suggestions?

Thank you.
