[Resolved] Can’t display repeatable group Fields in a php function

I am trying to: display fields in a repeatable group

Link to a page where the issue can be seen: hidden link

I expected to see: field values = Johannes 5,1-10; Matthäus 4,5; 1. Mose 5,1-8;

Instead, I got: nothing (see screenshot)

I have set up custom fields for the posts post type, one of them is a repeatable group called 'bibelstellen' and it contains a select field 'buch', and 3x number fields: kapitel, vers-von, vers-bis.
I can show these fields using a toolset view, but there are ristrictions my client cannot live with: I get extra <p> characters which I can't remove (tried for 3 hours!!) and I cannot use conditional output. (vers-bis can be emtpy sometimes and I need to hide the dash in such a case).

I NEED THIS TO WORK IN A PHP FUNCTION.

code in functions.php (I spent 8 hours looking through all the examples, they are incomplete or don't apply to repeatable groups):

//show Bibelstellen-repeating field
function bibelstellen_direkt_func()
{
$child_posts = toolset_get_related_posts(get_the_ID(),'bibelstellen', array('query_by_role' => 'parent', 'return' => 'post_object'));
if ($child_posts):
foreach ($child_posts as $bst) :
$bibref = (types_render_field( 'buch', array()));
$bibref .= (types_render_field( 'kapitel', array()));
$bibref .= (types_render_field( 'vers-von', array()));
endforeach;

return ($bibref);
endif;
return ('none');
}
add_shortcode( 'bibelstellen-direkt', 'bibelstellen_direkt_func' );
//I use the shortcode in my content template for regular wordpress posts

Can you please help me to get this function to work?

Ok - I've added the following code to the "Custom Code" section offered by Toolset:
=> hidden link

//Bibelstellen-repeating field direkt anzeigen
function bibelstellen_direkt_func1() {
  
 global $post;
  
  $child_posts = toolset_get_related_posts(
                                    $post->ID,
                                    'bibelstellen',
                                     'parent',
                                     100,
                                      0,
                                      array(),
                                     'post_object',
                                     'child'
                                     );
 if ($child_posts):
     $bibref = '';
	  foreach ($child_posts as $bst) :
		 $bibref .= (types_render_field( 'buch', array('item'=>$bst->ID)))." <br />";
		 $bibref .= (types_render_field('kapitel', array('item'=>$bst->ID)))." <br />";
		 $bibref .= (types_render_field( 'vers-von', array('item'=>$bst->ID)))." <br />";
	  endforeach;
	
	  return ($bibref);
	endif;
	return ('none');
}
add_shortcode( 'bibelstellen-direkt1', 'bibelstellen_direkt_func1' );

I can see now that its displaying the Repeating Field Group entries on the following page:
=> hidden link

You can remove the code you added to your functions.php file as its not used.
