What if it was accidentally licensed to your library not downloaded to your computer? I only noticed because the number of images available for download decreased and I went to my licenses and saw one I had not even seen and do not want FILE #: 161106945
As you have mentioned you have accidentally licensed a wrong image, As a gesture of goodwill I've added a credit to your account to replace the image licensed in error.
Let me know if that helps!
Feel free to update this thread in case of any additional query.
