I'm still having this problem. When I add a chapter to a book I usually 'copy citation' and edit data specific to chapter to save time. However when I go into a document to try to insert the citation I have the option of choosing the correct book chapter, however paperpile inserts it as the original citation I copied from. I've tried erasing the DOI, going into the 'duplicates' options and marking the chapter as not a duplicate, restarting paperpile, docs and chrome - nothing.
Option to chose correct citation:
What appears after I select:
"De Wall 2016" is also how it appears in the document.
Thanks in advance for any assistance.
