Formatting problem Endnote X and Word 2004

HI, I have a problem with my Word document in that some of the references are showing correctly and others have no coding and are showing the Record Number. All has been fine but managed to hit a key by mistake and now can’t repair the problem. I have tried unformatting and Fomatting Bib again but no luck. I am linking to 2 libraries so wonder if there could be an issue there? Hope someone can help. Regards, Bernie

If you unformat, do they all unformat?
