So when I look up my wallet address on a block explorer such as blocktrail or BTC.com it shows that I have received a total of 19 transactions totaling 0.09226983 BTC sent 12 transactions totaling 0.07334854 BTC and have paid a total of 0.00140960 BTC out for mining fees, leaving a current confirmed balance of 0.01892129 BTC but yet my wallet says that it's balance is zero...  Either Cryptonator "My wallet" has robbed me or maybe I'm just not understanding the block explorer results could someone please explain to me where this missing btc went?  
Or how and why it's not actually missing?  Any imput on this would be appreciated.

  Thanks
