ValidateOrder Creates 2 orders

[mattias-briq]

Hi all
Im trying to understand an issue i have with my custom payment module

It seems like for some reason that the orders are split  after i complete the paymentmodule::validateOrder call

cart = 1 item, regular demo item
order: 1 : Contains the correct cart - payment reference from my external psp and customer data
This orderis missing a carrier_id but has id_address_delivery and id_address_invoice set to correct values

order 2: Contains no cart at all, same customer details as #1, same psp reference as #1
This order has a carrier_id but is missing the id_address_delivery

I understand that Prestashop has a history of splitting orders between warehouses and carriers etc, however this order only has 1 item, with 1 package

Anyone came across something similar recently?
This is on latest presta 1.7.7.2
