@wendy: It’s not the page. It’s the function that controls the homepage headlines. So, if you want to edit this then first you need to build child theme and create new functions.php file in your child theme and then copy function catchkathmandu_homepage_headline() from catchkathmandu-functions.php file and paste it in your child theme functions.php file. Then need to replace the following code
if ( ( is_front_page() || ( is_home() && $page_for_posts != $page_id ) ) && ( empty( $disable_headline ) || empty( $disable_subheadline ) || empty( $disable_button ) ) ) {
with the following
if ( empty( $disable_headline ) || empty( $disable_subheadline ) || empty( $disable_button ) ) {
This is bit technical. So, I hope you understand it.
