I´m not Parodium, but I think I know the answer to this question.

You just have to take a look at the bottom of the payment transaction:

When making a BTC transaction with multiple outputs the transaction that is displayed at the bottom is always
specifying where the remaining funds (= the change) ended up.
After making all signature payouts 0.50367627 BTC were unused and ended up in the change address.
