Biblio en double
Hello everyone, I have a problem with a reference that is written twice with ref a and ref b, even though it is the same reference; indeed I go to the library, I delete one then the 2 references, nothing changes, it is still there even though I can't find it in the library, how is that done?
Now this stray item still lives in your document. Delete it wherever you cited it in the text and reinsert the item. That will remove it.
