My wallet balance when viewed on Blockchain.info isn't matching what I see in my Bitcoin-Qt wallet.

Here are the transaction showing in my Bitcoin-Qt wallet: 19JjdmUFikrRgZ1FtJvajQL8cX1QN9ZcHx

In 8.58094
Out -2.5005
Out -2.5005
Out -2.0005

Balance 1.57944 BTC

But, when I view my wallet address at Blockchain.info I see this: http://blockchain.info/address/19JjdmUFikrRgZ1FtJvajQL8cX1QN9ZcHx

Please help me understand...
