This is perfectly normal. When you set a page as front page WordPress thinks that you want to use the home url for it.

Said that, the url for your calientes page will be your home url (http://domain.com). Now, front pages are not intened to use pagination, so if you put /page/{number} on a fron page it is considered the 'page' query var, not the 'paged', so if you have it as fron page you have to use:

$var = is_front_page() ? 'page' : 'paged';
$paged = ( get_query_var($var) ) ? get_query_var($var) : 1;

However, if you want the url stay http://domain.com/calientes/ (this will became your home url) you need a redirect and do not set 'Calientes' page as home page.

add_action('init', 'calientes_home');

function calientes_home() {
   $fullurl = add_query_arg( array() );
   $url = explode('?', $fullurl);
   $parts = array_filter( explode('/', trim($url[0], '/') ) );
   if ( $parts[0] == 'page' && is_numeric($parts[1]) ) {
     wp_redirect( home_url('/calientes/page/' . $parts[1] ), 301 );
     exit();
   } elseif( $parts === array() ) {
     wp_redirect( home_url('/calientes/'), 301 );
     exit();
   }
}
