If the Nested Form field has no label, the default output might look something like / Child field label. This snippet will update that to Child field label (no slash).

add_filter( 'gpnf_export_child_field_header', function( $header, $form, $field, $child_field ) {

    $parent_label = $field->get_field_label( false, null );
    if ( empty( $parent_label ) ) {
        $header = $child_field->get_field_label( false, null );
    } else {
        $header = sprintf( '%s / %s', $parent_label, $child_field->get_field_label( false, null ) );
    }

    return $header;
}, 10, 4 );
