Mail Merge Form issue – lose Word document references

I am trying to use mail merge to input various data points into a Word document.  The Word document uses a styles outline with various inserted references to other sections throughout the documents.  When I preform the merge, it inputs the data from the Excel source spreadsheet, keeps the styles outline, BUT it converts all the internal references to the style sections.  I need these references links to stay active links. 

Microsoft Support recommended I post this issue to here.  Thank you for any help!
