Wrong counter value

[ZeynabKhani]

I followed the steps on the second tutorial found in this link: http://tonhelloworld.com/02-contract/. I called the sendIncreament deploy script and my transaction is confirmed on the explorer, yet when I call the getCounter script by blueprint, it shows me the previous counter amount (not incremented). Could this be an error of testnet or is it a problem with the contract itself?
