Free Shipping data not send

I’m using Magento 2 with Moloni plugin, and I need that the invoice have the free value but if I’m not wrong when it’s free it does not send the data so it does no appear in the invoice, if I define a value it works just fine but when it’s free or 0.00 it does not appear.

Any way to work around this?

Thanks in advance
