If you delete the first one, everything is okay.
I've seen, that the epub was generated by Calibre. Somebody else reported the same problem with another epub which is located at Mobileread: https://www.mobileread.com/forums/showthread.php?t=62489
I don't know if this duplicate meta tags occur because the creator made an error or if this is an error of Calibre itself. I'll post this at the Calibre thread and will see, what they say.
