I used a back cover from the gallery for another book, and it showed the other book's text. What should I do?

From version 1.9.20 this no longer happens. When you pick a back cover from the gallery for a book, and the artwork it was made from is still there, BookyAI takes that artwork and writes this book's own description and author text on it. Before, the gallery picture was used with the other book's words baked in. A back cover that was uploaded, or whose original artwork was replaced since, is still used as the finished picture it is. If a book already has a back cover with the wrong text, pick it again from the gallery on the book's page.
