Multiple output transaction, unknown recipient

[DogecoinMachine]

I made a transaction with multiple outputs:
https://blockchain.info/tx/00f555d5d9699c4de8e26cff9b5f2408b1ab7ddc3fd1c0b8524d23c787d75e55

But there is one address I didn't send any amount (it was added automatically):
1GxVeeNejY4Gevo1AKFoozsY9ntJ6BFJx7       0.01000062 BTC


Here's another transaction:
https://blockchain.info/tx/9c0cdf93ff2fefb81a87b6590610f7f4fe0db7f2c5b10bdcd48bb5ab8d6804f6

and with similar extra amount:
1BWTnbd6LTQDVSAPJMQcMxcWJad6ACqTEq       0.01000306 BTC


Who is this address and why is automatically added into transaction?
Transaction fee was in both cases set to max 20k satoshi.

Make sense. Thank you!
