Endnote Highlighting Issues

Thanks so muchly for your input.  I think I may know the problem.  I had 2 separate word documents, being chapter 1 and 2.  Then I combined chapter 1 and 2 into a single word document and it was chapter 2 that was completely highlighted.  I just tried the unformat citations, grey did not disappear.  Then I did the alt-9, not really understanding what it does and grey disappeared.  I did reformat and it seems it worked.  I guess something happened when I combined the two chapters.  Is there something I should have done when combining 2 word documents? Now my one document has 2 bibliographies which is what I want.  I think has all formatted properly.  I’ll see if I can work with this.  Thank you so much for your help.
