Getbalance shows 0 but explorer shows 2 btcz

Hi

I installed bitcoinz on my machine. I’ve send 2 btcz on address: t1aieBLQB3KSfTT6WjP3pkWERKecjoxT1dq
And when I check on explorer btcz rocks I can see my 2 btcz.

But when I call getbalance on my node it shows me 0:
./src/bitcoinz-cli -datadir=/home/bitcoinz/data z_getbalance t1aieBLQB3KSfTT6WjP3pkWERKecjoxT1dq
0.00000

What is the reason?
