I have done below modifications in your website:
1) Modify the PHP codes as below:

add_shortcode('remove-empty-lines', function($atts, $content){
  	$atts = shortcode_atts( array(
        'field' => 'wpcf-issue',
    ), $atts );
  	$res = '';
  	$value = '';
  	if(isset($atts['field'])){
    	$value = get_post_meta(get_the_ID(), $atts['field'], true);
      	$value = trim($value);
    }
  	if(empty($value)){
      $res = do_shortcode($content);
    }
    return $res;
});

2) Modify the shortcode in content template as below:
[remove-empty-lines]nicht verfügbar [/remove-empty-lines]

Please test again, check if it is fixed, have a nice day
