Elementor group skin not working

Hi,

I have created an elementor group skin, but when outputted into my template, it repeats the first line of the array in the number of repeatable sections there are (So if there are 5 values, then it repeats the first value 5 times).

I tried to redo it, but still the same error. The saved data is correct, just the output which is problematic.

[
                'name'       => __( 'Recommendation Multiple', 'your-text-domain' ),
                'id'         => $prefix . 'recommendation_multiple',
                'type'       => 'group',
                'clone'      => true,
                'sort_clone' => true,
                'fields'     => [
                    [
                        'name' => __( 'Actionable Recommendation', 'your-text-domain' ),
                        'id'   => $prefix . 'recommendation',
                        'type' => 'textarea',
                    ],
                ],
                'tab'        => 'academicsummary_tab',
            ],

I have another group skin that works. Only difference, is that that one is not sortable.

Do you know what could be going wrong?
