Adding an Internal member account requires that the account has not been previously used.  When a Merchant Account is created, a Smart Account with the same account and password will be generated simultaneously. After deleting a Merchant Account, the Smart Account needs to be simultaneously deregistered before it can be added as an Internal member account.
