If you’re using shortcodes to add ACF fields to pages then your going to need to build a custom shortcode which will require adding code to the theme’s functions.php file or possibly some other file depending on your theme.

You can start here https://codex.wordpress.org/Shortcode_API

There are some tutorials and guides available like this https://www.wpbeginner.com/wp-tutorials/how-to-add-a-shortcode-in-wordpress/ and this https://www.smashingmagazine.com/2012/05/wordpress-shortcodes-complete-guide/

This is the basic shortcode code in ACF for a reference.

/*
*  acf_shortcode()
*
*  This function is used to add basic shortcode support for the ACF plugin
*  eg. [acf field="heading" post_id="123" format_value="1"]
*
*  @type  function
*  @since  1.1.1
*  @date  29/01/13
*
*  @param  $field (string) the field name or key
*  @param  $post_id (mixed) the post_id of which the value is saved against
*  @param  $format_value (boolean) whether or not to format the field value
*  @return  (string)
*/

function acf_shortcode( $atts ) {
  
  // extract attributs
  extract( shortcode_atts( array(
    'field'      => '',
    'post_id'    => false,
    'format_value'  => true
  ), $atts ) );
  
  
  // get value and return it
  $value = get_field( $field, $post_id, $format_value );
  
  
  // array
  if( is_array($value) ) {
    
    $value = @implode( ', ', $value );
    
  }
  
  
  // return
  return $value;
  
}

add_shortcode('acf', 'acf_shortcode');
