Just delete it and repost in the custom section. To delete, go to your first post, hit Edit, then hit Edit again, then click the delete this post option (it will delete the thread). It's a great sculpt, by the way.
My bad, after you click Edit the first time, click "go advanced". Then, the delete option should be right at the top with a "Delete this Message" option, you'll need to click a bubble confirming that you want to delete the message before clicking the Delete button.
