Updated theme and applied a shortcode

Hi. I updated the theme and applied a shortcode for another slider in the header.php i placed the shortcode after do_action( 'create_after_header' ); and now i get this line under the slider on the webpage. https://www.klosterkaelderen.beer/ /** * create_content hook * * @hooked create_content_start - 10 * @hooked create_intro_sidebar - 20 */ do_action( 'create_content' ); how do i remove that line from the webpage.
