see your total balance in above menu of your blockchain.info's account dashboard, maybe you just generate a new address and it being set up as your main address but the balance still in your old address,you'll only lost your bitcoin if you lose either your address in your wallet and your privkey
I sent a 0.001btc as a test from my secondary wallet and it shows as balance now, however I'm not entirely sure why I no longer can see the wallet adress in my bitcoin adresses.
hopefuly the bitcoins that I requested will be recieved
