Shopify - Sales Order shipping item


we use the setting of the e-commerce extension that the shipping costs are imported as an item in the sales order. The item has been configured so that the stock is not managed.

Nevertheless, the shipping item must be included in the delivery, otherwise the sales order is not marked as completed, or the sales order must be closed manually.

What is the intended path here?
It seems to me that the team has not thought this through to the end, can anyone say more about this?

Thanks! Luke
