Hi, I just purchased the 3d flipbook.

When I’m trying to add the books I’ve created as a shortcode with visual composer something goes wrong. Only one book appears but I can’t add the other books. Then after a while visual composer is not loading. I’ve tried this many times with different browsers but the problem keeps coming back.
