You can get these addresses also in the "receive" tab. Even though the addresses look the same, they are on different networks, in fact, they are different accounts, but identified with the same name.

			To send coins from one network to another, special technology is required called a bridge. In Metamask the bridge technology is hidden in the "Swap" tab, if you just send tokens from one network to another they get lost.
