When loading a poster I accidentally created a duplicate subject for the band Jucifer, see https://posters.discogs.com/subject/136077-jucifer. I changed the poster so that it aligns with the main Jucifer heading. Can someone delete this empty subject so that it doesn't get used again (or tell me how I can do it).
Click on "Edit this Subject", erase the Title (in this case: Jucifer) and put in Duplicate, go to the "Submission Notes" section and explain what you did, in this case: marked accidentally created Subject as duplicate, press "Submit" button.
