Magento version

What went wrong?

When I create an order in backend I need to select a shipping method, this is a required field. But after updating Myparcel from 4.10 to 4.12.1 this is not working anymore. (4.11 also does not work).
In the field a message displays:
You don't need to select a shipping method.
But when I submit the order I get the message this is a required field.

Reproduction steps

1. Navigate to Sales-Orders-Create New order
2. Select existing customer
3. Add products to the order
4. Submit Order
