We have set up Segmentation Criteria for Payment Order and Customer Payment. The two segments transfer OK, we get two separate Mixed Payments that are OK. But the remaining transactions gets transferred with the total sum of the external payment, i.e. not the sum of the remaining transactions. As a result, the Mixed Payment will try to create a parked payment for the residual. 

What do you think? Is this something we can fix with some basic data setting or is it a bug?
