Zotero has automatically overwritten footnote citations in a document. Some footnotes now display text that differs from what was originally in the Zotero library, even though the underlying fields remain active and linked the right footnote (it just appears different in the text). As I didn't expect that, I accepted manual changes, why I can't see now, where it all happended. How can I figure out, which footnotes Zotero unfortunately changed by itself as it is not asking me again. I am very looking forward for help, as it is my PhD-thesis we are talking about...
