3D FlipBook - How to create book short code with RTL property ? And Does Pro version supports Arabic language?

I am using free version. I created this shortcode to display the book in rtl direction [3d-flip-book mode="link-lightbox" urlparam="fb3d-page" rtl="1" pdf="test.pdf"]text [/3d-flip-book]. But I am not getting the result. Note: Creating book from admin panel and checking rtl in book properties tab works fine for the generated book.
