iBooks Author Keynote widgets show the same slideshow

If you have more than one period in the filename of your Keynote presentation, your slideshows might appear to have identical slides when you view your book in iBooks.

Before you add your Keynote presentations to your iBooks Author book, make sure that their filenames do not contain any periods other than the one in the .key extension. Replace any extra periods with other characters, such as a dash or underscore. For example, name your slideshows Slideshow_001.key or Slideshow_002.key, not Slideshow.001.key or Slideshow.002.key.

If you have any Keynote widgets in an iBooks Author book that look the same when you view them in iBooks, rename the Keynote files. Then re-add the Keynote widgets to your book.
