MySQL: Perché ricevo questo avvertimento?

Question

Sto chiamando la procedura memorizzata di seguito e ricevo questo avvertimento, questo avvertimento è un falso positivo o la mia domanda non è sicura?

1 queries executed, 1 success, 0 errors, 1 warnings

Query: call User_Signup('lee3@gmail.com', 'password', 'Lee', 'Brooks', null, null, null, null)

1 row(s) affected, 1 warning(s)

Execution Time : 0.042 sec
Transfer Time  : 0.093 sec
Total Time     : 0.136 sec

Note Code : 1592
Unsafe statement written to the binary log using statement format since BINLOG_FORMAT = STATEMENT. Statements writing to a table with an auto-increment column after selecting from another table are unsafe because the order in which rows are retrieved determines what (if any) rows will be written. This order cannot be predicted and may differ on master and the slave.

Ecco la chiamata:

CALL User_Signup('lee3@gmail.com', 'password', 'Lee', 'Brooks', NULL, NULL, NULL, NULL);

Ecco la procedura memorizzata:

DELIMITER $$

USE `MobiFit_Dev` $$

DROP PROCEDURE IF EXISTS `User_Signup` $$

CREATE DEFINER = `root` @`localhost` PROCEDURE `User_Signup` (
  email VARCHAR (250),
  hashedPassword BINARY(60),
  firstName VARCHAR (100),
  lastName VARCHAR (100),
  gender ENUM ('Male', 'Female'),
  dateOfBirth DATE,
  height DECIMAL (3, 2),
  currentWeight DECIMAL (4, 1)
) 
BEGIN
  INSERT INTO USER (
    Email,
    HashedPassword,
    RoleId,
    FirstName,
    LastName,
    Gender,
    DateOfBirth,
    Height,
    CurrentWeight,
    CreatedAt
  ) 
  VALUES
    (
      email,
      hashedPassword,
      (SELECT 
        id 
      FROM
        Role 
      WHERE `Code` = 'CUSTOMER'),
      firstName,
      lastName,
      gender,
      dateOfBirth,

    ) ;
END $$
