Trigger is not inserting some columns value - sql-server

Question

I am working in two table. one is AspNetUser and second is App_User so I am adding any records in aspnetuser then one trigger will be fire and it will add that same data in app_usr table.
But in my case there is one issue all other values of records is inserting in app_user table but there is 2 values is not inserting in new table
AspNetUser Table schema:
CREATE TABLE [dbo].[AspNetUsers](
[Id] [nvarchar](128) NOT NULL,
[Email] [nvarchar](256) NULL,
[UserName] [nvarchar](256) NOT NULL,
[FirstName] [nvarchar](50) NOT NULL,
[MiddleInitial] [nvarchar](1) NULL,
[LastName] [nvarchar](50) NOT NULL,
[AccountID] [int] NOT NULL,
[SystemLevel] [int] NOT NULL,
[CreatedBy] [int] NULL,
[active] [bit] NOT NULL,
[VendorAccountID] [int] NOT NULL,
[VendorUser] [bit] NOT NULL,
CONSTRAINT [PK_dbo.AspNetUsers] PRIMARY KEY CLUSTERED
(
[Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
Please see below is App_User's schema:
CREATE TABLE [dbo].[App_User](
[ID] [int] IDENTITY(1000,1) NOT NULL,
[account_id] [int] NOT NULL,
[system_level] [int] NOT NULL,
[logon] [char](256) NOT NULL,
[first_name] [char](50) NULL,
[middle_initial] [char](1) NULL,
[last_name] [char](50) NULL,
[email] [char](256) NULL,
[description] [char](250) NULL,
[created_by] [int] NOT NULL,
[creation_date] [datetime] NULL,
[modified_by] [int] NULL,
[modification_date] [datetime] NULL,
[active] [bit] NOT NULL,
[default_approver] [bit] NULL,
[vendor_account_id] [int] NULL,
[vendor_user] [bit] NOT NULL,
PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF) ON [PRIMARY]
GO
Please verify I have inserted below trigger's code:
CREATE TRIGGER [dbo].[Tr_aspnet_Users_CreateUser] ON [dbo].[AspNetUsers]
AFTER INSERT
AS
DECLARE #AccountID int
DECLARE #VendorAccountID int
DECLARE #VendorUser bit
DECLARE #SystemLevel int
DECLARE #UserName varchar(256)
DECLARE #FirstName varchar(50)
DECLARE #MiddleInitial varchar(1)
DECLARE #LastName varchar(50)
DECLARE #Email varchar(256)
DECLARE #CreatedBy int
SELECT #AccountID = i.AccountID from inserted i;
SELECT #VendorAccountID = i.VendorAccountID from inserted i;
SELECT #VendorUser = i.VendorUser from inserted i;
SELECT #SystemLevel = i.SystemLevel from inserted i;
SELECT #UserName = i.UserName from inserted i;
SELECT #FirstName = i.FirstName from inserted i;
SELECT #MiddleInitial = i.MiddleInitial from inserted i;
SELECT #LastName = i.LastName from inserted i;
SELECT #Email = i.Email from inserted i;
SELECT #CreatedBy = i.CreatedBy from inserted i;
IF(#VendorAccountID=0)
SET #VendorAccountID=NULL
BEGIN
SET NOCOUNT ON;
INSERT INTO [dbo].[App_User]
([active]
,[account_id]
,[system_level]
,[logon]
,[first_name]
,[middle_initial]
,[last_name]
,[email]
,[vendor_account_id]
,[vendor_user]
,[created_by]
,[creation_date])
VALUES
(1
,#AccountID
,#SystemLevel
,#UserName
,#FirstName
,#MiddleInitial
,#LastName
,#Email
,#VendorAccountID
,#VendorUser
,#CreatedBy
,GETDATE())
END
GO
Now Issue is that while trigger fires then all other value is inserting properly but vendor_account_id and vendor_user is not inserting.
Can anyone please help what should be issue here.
