Contact ID Does Not Increment By 1

For some reason, the primary id does not increment by 1 but by 32. I know I used the exact same code from the video.

The code below solved the problem, but I want to know why I'm having this problem.

    @GenericGenerator(name="increment" , strategy="increment")
    @GeneratedValue(generator="increment")
    private int id;

Try this : @GeneratedValue(strategy = GenerationType.TABLE)

Hey Jeff, did you mark your int with the annotation @Id? The only two annotations should look something like this. 

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)

Yes, I did mark it with "@Id"

Hey Jeff, it might be a moot point, but can you paste all of your code and XML configuration file, I'll take a look at it, and see what I can find.
