Good afternoon.
You have not specified the setting "Ignore the amount of the subprocess" - in fact, in addition to the amount of the specified process - it takes the amount of the subprocess
https://topbox.1b.app/11470/ - the sum is 740.
Further, since it is indicated to make an outgoing payment and the "Include process payments" setting - checks for outgoing payments to the client to minus the amount - there are none.
So it turns out the payment for 740 UAH.
Solutions 2:
1. set the setting "Ignore the amount of the subprocess"
2. finalize something, taking into account incoming payments
