Help with changing wallet address - Monero

[lncm]

Is this normal? Help a newbie here.

I created a monero wallet 2 months ago to start mining.

Now that I am almost being paid, I checked wallet adress, and it isn't what entered on pool miner configurations.

After some googling, I went to https://xmr.llcoins.net/addresstests.html both are valid monero adresses, but suposedly "Netbyte + 10" should be the same and it isn't.

What am I missing?

Thanks.
