Book won't add to series

[A.L.]

Hi, I would like The Stolen Tower added to the Light Beyond The Storm Chronicles Series. I've put the series name and book number in parenthesis as advised but for some reason it doesn't link to the other two books.

Not sure what I've done or haven't done. Please help oh kind librarians:)
