Dupe character in journal but linked to the same sheet

so i somehow misclick/drag something wrong and roll20 decided to dupe a character sheet in my journal menu. whenever i change one of the sheet it changes the other so both characters are linked to the same sheet, but I don't want to delete duped as it will delete the original as well.  It happened on another monster/character, I deleted the extra item and it deleted the original item, so obviously i don't want to repeat the mistake again here since it's a character sheet and it takes a a long time to build it.  Anyone can help ? thanks

Hi Drespar, thanks for the reply. I moved the 2 items at the bottom. Keep in mind that only one needs to be removed. Journal entries are named "Ganaraël" in the campaign id 2255689. I do not know exactly how i did it but it happened to me twice (the first time i deleted one of the entry and they both disappeared). It was a combinaison of  misclicking/dragging the entry.. Sorry I can't be more precise. If I can replicate i'll send log and how it happened.. Thanks!
