HAVING DIFFICULTY CHANGING MY "BITCOIN ADDRESS"

[Eggsandbaconforbrekkie]

Hi!

I am having difficulty changing my “bitcoin address” on my profile.  I am trying to erase the address that is currently on my profile to replace it with a new bitcoin address.  I don’t understand why, but my new Bitcoin address is not replacing my old one.  Each time I look at my profile or go to the Faucet my old bitcoin wallet address is present.
Can you suggest anything in regards to help me changing the bitcoin address on my profile?

Thanks.
