Issue with cover jacket in Photos

Dear All,

Since I have changed form iPhoto to Photos for Mac, I have an issue with generation of cover jacket. By the past (with iphoto) a cover Jacket was generated in 1 page and the title of the book was on the side of the cover jacket.

Now with Photos, it generates 4 pages instead of 1, so when you buy the book generated by the new PDF it's a complete mess and there is no more title of the book on the side of the book.

Is there any solution to this issue
