Exporting citations using Word's built-in citation feature with the Bibtex Export style not working.

Damsz

Hello! I'm new to Zotero, and was trying to export my word bibliography to Zotero. I followed these steps, suggesting the use of the Bibtex Export style, to then copy the bibliography and importing it into Zotelo through the clipboard. However, when I select the Bibtex Export style, citations appear as "Invalid source specified" and the bibliography as "There are no sources in the current document", so I'm unable to copy it. The style seems to have been added correctly, since when hovering over the Word's Bibliography button, it shows examples of it such as author = {} and other fields.

Any help would be very much appreciated.
Cheers!
