I'm using Bitcoin Core version v0.12.1 (64-bit). When I create a new receiving address and look it up on blockchain.info it shows that transactions already exist with that address. How is this possible? Should a brand new address have zero transactions associated with it?
For example, I just created this new address "1NJXy8JSSUYjRp7V83thvUbMG1DBuKA6wc". When I look it up on blockchain.info we see two transactions.
