I get a json response which I can not figure out if it has some sort of error or that I'm mistaken.

The response show results in transaction 1206412 = 0.01206412BTC added to balance 0BTC should get 1206412 = 0.01206412BTC, however we get balance = 1201206412 = 12.01206412BTC, I think it's error in blockchain.info api or could you explain how the balance is calculated.
