Hi there,

There is a strange issue happening only to your site, where the ID of the shop page is being set to 0 so it is applying the transparent header to the shop page only, to fix that we have added this code under functions.php of the child theme:

add_filter( 'acf/pre_load_value', function( $return, $post_id, $field ) {
    if ( 0 === get_queried_object_id() && 'enable_transparent_header' === $field['name'] ) {
        return false;
    }
    
    return $return;
}, 10, 3 );
