The value in the table is null, but the cdc results is 0

demo:

CREATE TABLE [dbo].[AA_test] (
  [id] int  NOT NULL,
  [name] varchar(255) COLLATE Chinese_PRC_CI_AS  NULL,
  [age] int  NULL,
  [phone] varchar(50) COLLATE Chinese_PRC_CI_AS  NULL,
  [number_0] bigint DEFAULT ((0)) NULL,
  [datetime_0] datetime  NULL,
  CONSTRAINT [PK__AA_test_ID] PRIMARY KEY CLUSTERED ([id])
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON)  
ON [PRIMARY]
)  
ON [PRIMARY]
GO

ALTER TABLE [dbo].[AA_test] SET (LOCK_ESCALATION = TABLE)

-------------------------------------------------------------------------

INSERT INTO [dbo].[AA_test]([id], [name], [age], [phone], [number_0], [datetime_0]) VALUES (7, 'tester', 1, '911', NULL, NULL);

-------------------------------------------------------------------------

In the table number_0 = null, but in the collected data, number_0 = 0

I know number_0 default 0 in ddl, but l hope cdc results are consistent with the actual values

Is there any way to adjust it?
