Bug in changing the label with multiple items?

I'm using field_group with field_collection. I'm *pretty sure* the problem is on field_group, but not 100% sure.

This is a product feedback tool.

I need a way to pre-load up 5 different products so I used this: https://drupal.org/comment/8462791#comment-8462791

It works great.

Let's assume this:

function custom_form_feedback_node_form_alter(&$form, &$form_state, $form_id) {
 
        $items_count = 6;
        $field_name = 'field_fieldcollection';
        $form_theme = $form[$field_name][LANGUAGE_NONE]['#theme'];
 
        // Remove delete and add more buttons
        $form[$field_name][LANGUAGE_NONE][0]['remove_button']['#access'] = FALSE;
        $form[$field_name][LANGUAGE_NONE]['add_more']['#access'] = FALSE;
        $items = &$form_state['field'][$field_name][LANGUAGE_NONE];
 
        // Generate required number of fields collection
        if ($items_count > 1 and $items['items_count'] != $items_count) {
          $items['items_count'] = $items_count;
          $items['field']['cardinality'] = $items_count;
          $form[$field_name][LANGUAGE_NONE] = field_multiple_value_form($items['field'], $items['instance'], LANGUAGE_NONE, array(), $form, $form_state);
 
            // Reset theme function, as field_multiple_value_form hijacks it
            $form[$field_name][LANGUAGE_NONE]['#theme'] = $form_theme;
        }
echo 'Going in';
        // Fill generated fields with data
        for ($delta = 0; $delta < $items_count; $delta++) {
          $form['field_fieldcollection'][LANGUAGE_NONE][$delta]['#groups']['group_feedback_name']->label = "Feedback for ".$delta;
        }
}

Here is the line where the label should be set:

$form['field_fieldcollection'][LANGUAGE_NONE][$delta]['#groups']['group_feedback_name']->label = "Feedback for ".$delta;

The problem: The label always ends up as "Feedback for 5". (5 is the last item that gets looped through since count starts at 0)

Here is the array that it's modifying

   [#groups] => Array
                        (
                            [group_feedback_name] => stdClass Object
                                (
                                    [id] => 5
                                    [identifier] => group_feedback_name|field_collection_item|field_feedback|form
                                    [group_name] => group_feedback_name
                                    [entity_type] => field_collection_item
                                    [bundle] => field_feedback
                                    [mode] => form
                                    [parent_name] =>
                                    [table] => field_group
                                    [type] => Normal
                                    [export_type] => 1
                                    [disabled] =>
                                    [label] => Feedback for Full team 5 member delta4
                                    [weight] => 0
                                    [children] => Array
                                        (
                                            [0] => field_feedback_fielda
                                            [1] => field_feedback_fieldb
                                        )
 
                                    [format_type] => fieldset
                                    [format_settings] => Array
                                        (
                                            [formatter] => collapsible
                                            [instance_settings] => Array
                                                (
                                                    [description] =>
                                                    [classes] =>
                                                    [required_fields] => 1
                                                )
 
                                        )

                                )
 
                        )

What I've done:
1. I've tried changing the id and weight, no luck.
2. I put an echo $delta in the loop and it DOES iterate properly: 0, 1, 2, 3, 4, 5. So I know it's working (I also change other fields in the code and it works fine)
3. I noticed that when I changed the field group from a div to html in manage fields, it changes title properly! Very strange.
4. I tried setting weights on my module/node_group - no go.

I'm thinking something is overriding the label but I cannot figure this out and I've spent hours on it.
