The Include process payments setting does not work

Good evening. Initially, the process was created as outgoing, later you changed the direction to incoming in the business process, but it did not change in the process (to change the direction of the process, you can use the action at the stage)
As a result, when creating a payment, the process amount was taken -1500. payment is incoming, then we also look for previous payments incoming and subtract from our amount, we get -1500-1500, and since the payment must be made from the client, the amount is rounded up and we get a new payment by 3000
If you try to repeat all the same on a new process, the second payment will not be created due to the fact that payments for a zero amount are not made
