Thanks for your response. Fixing the breadcrumbs got rid of the blank space between the navigation bar and the revolution slider.
However, the Navigation bar in the second language (Catalan) does not display the orange navigation bar indicators as the English version does. Note that the navigation bar in second language does have a default option (“Inici” means “Home” in Catalan). http://www.catalaninstituteofamerica.org/ca/
