Most likely, the error occurs in your EAD template. It seems that you are using the NCEAD toolkit, which utilizes NoteTab. If you are using NoteTab, go to "File" --> "Template" --> "Edit" and then select the proper .tpl file. (If you are unsure, you can right-click the "Create New Finding Aid" clip from the clip library and find the name of the file. If you are using the default NCEAD_2002rev clips, the file is likely named "template2002rev.tpl". The default location for the NCEAD Template is notetab/Templates/template2002rev.tpl)
One quick way to make the changes would be to CTRL+ F and search for "Preferred Citation." There, you will likely find the "Boone, North Carolina, NC" phrase, which you may alter.
As to past finding aids, I only know of running a find and replace on the individual EAD files, but someone on the list might know a better way to globally alter the batch.
Hope this helps!

Looking at the actual EAD, it looks like it's actually in there as
such, meaning you need to fix the underlying code.
