Problem dynamically loading options for a child of repeater field

Hello,
I’ve used this function in the past to load the possible values of a field.

add_filter('acf/load_field/name=combine', 'load_combine_fields', 10, 3);
function load_combine_fields($field)
{
	$productGroupID = $_GET['tag_ID'];
	//get the field value of "filter" from the product group without loading the field
	remove_filter('acf/load_field/name=combine', 'load_combine_fields', 10, 3);
	$filters = get_field('filter', 'product_group_' . $productGroupID);
	add_filter('acf/load_field/name=combine', 'load_combine_fields', 10, 3);

	$field['choices'] = array();
	if ($filters != null && is_array($filters)) {
		foreach ($filters as $filter) {
			$options = $filter['filter_options'];
			foreach ($options as $option) {
				$field['choices'][sanitize_title($option['value'])] = sanitize_title($option['value']) . ' (' . $filter['filter_title'] . ')';
			}
		}
	}
	error_log(print_r($field['choices'], true));
	//$field['choices'] = array('1', '2', '3', '4');
	return $field;
}

Nowadays it does not do anything. The log is beeing created so the function IS running, but the field options are just not beeing set.

Note: I think it has something to do with the “combine” field beeing a child of the repeater field “filter”. If I move the field outside the repeater, everything works.
Also: If i comment out everything but the hard coded choices at the end, the options are beeing set as 1,2,3,4.

Thanks!
