This has been asked before here: “Preventing duplicating during copying online references”

However, it still has not been resolved yet.
- You search online PubMed for references and e.g. found 5 refs.
- You want to retrieve ref #1-5.
- If you have turned on “automatically discard duplicates”, those that are duplicates in your library will not be retrieved. You will not have a chance to see what they are.
But if you have turned off “automatically discard duplicates”, all the 5 refs will be retrieved. - Now you want to add them to your local library. All the 5 refs will be copied/pasted to your library even if you have tuned on “automatically discard duplicates”.
Ideally, at step 3, all 5 refs should be retrieved, so you have a chance to see what have been found. then at step 4, if those to be moved into your local library are possible duplicates, you will be reminded to stop it. this will give you a chance to abandon it, e.g. checking before copying/pasting. This is the way that “Reference Manager 12” uses to deal with possible duplicates. I wonder why EndNote handles it in such a bad way!
In addition, EndNote now treats “Smith, H.K.” and “Smith, H. K.” (a space between H. and K.) as different authour names when determining if two references are possible duplicates.
