Pdf attached to a wrong record. Unattach?

Hi,
I have a pdf that has a reference to another article via DOI. I want to add the pdf to my library as a new record, but paperpile keeps attaching it to the mentioned paper.
Any workaround about it?

If the item in your library and the PDF you’re trying to upload have the same DOI, the importer will always flag it as a duplicate. You could try temporarily deleting the DOI from the existing reference, uploading the PDF and re-adding the DOI if successful. Let me know if that doesn’t do the trick.
