How to put the second last name

[Gonzalo]

Hi, I add this book and in author information I add the name "Daniel Seisdedos Reyes" then when the book appear on my books it looks like it took "Seisdedos" as middle name when for real "Seisdedos" is the last name.
What to do in the case an author put the name and his two last names??
In this particular case
Daniel / First Name
Seisdedos / Last Name
Reyes / Second Last Name

Thanks

I've corrected the author's sorting. Better now?

Thanks Its right now.

Ask here in the Librarian Group. It has to be corrected after the author profile is created.
