As the project owner, you may not have the ability to delete an attachment once your submission has gone through. Some Licensors may have this option disabled for Licensees. If you don't see the option to delete in your account, Attachments can be removed/replaced by Lead Reviewers or Site Admins. In this case, please reach out to your Licensor contact and provide them with the project number and file name you wish to have the attachment deleted from.
