Word cannot be added because it is a duplicate (WR)

[benkw26]

I was configuring the webhook so I added a word to my Anki deck.
I had to change the deck it was saved to (by changing the storage contents), then I deleted the card as it was in the wrong deck. I then tried to add the same word onto the correct deck and it says duplicate. How can I remove this log so I can add this word?
