Error when adding two or more citations with same author name and title but different date

I’ve noticed that when I try to add two items – which have the same author name and title, but a different date – after adding the first one, I get a “Whoops — this citation already contains the selected reference!” message.

Update: I altered the author name and it didn’t fix it, but when I edited one of the titles, it could add it fine (but now the title is wrong :wink: )
