Magento 2 option products of bundle are not showing in my orders magento core

Question

I need the Qty of bundle options that I have ordered.

I can see getChildrenItems() on getting the count it returns me 1, it doesn't include child products.

Bundle/templates/sales/order/items/renderer.phtml

$items = array_merge([$parentItem], $parentItem->getChildrenItems());

renderer.phtml loads for both my orders and print order, For print I can see child product.

My Order

Print Order

How can i get the list of child products and the Qty ordered.

With your core module Sales Remove

Magento/Sales/Block/Order/Items.php
//$this->itemCollection->filterByParent(null);
