2 Inserts into Inserted table Why?

I have the below Trigger. When it fires it sends 2 records identical to the PArcel_History Table. What is the reason why?

USE [CNTY_GIS]
GO
/****** Object:  Trigger [dbo].[Changes_To_Parcel_History]    Script Date: 06/13/2013 14:51:39 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER TRIGGER [dbo].[Changes_To_Parcel_History] 
ON  [dbo].[Parcel]
After UPDATE

AS 

IF 
UPDATE (Geometry) 
OR UPDATE(OP_Designation) 
OR UPDATE(OP_Amendment_No)
OR UPDATE(Zone_Name) 
OR UPDATE(Parcel_ID) 
OR UPDATE(Roll_Number)
OR UPDATE(Zone_Bylaw_No)
OR UPDATE(Zone_Schedule_Name)


 INSERT INTO Parcel_History
 ([geometry], [OP_Designation], [OP_Amendment_No] ,[Zone_Name],[Parcel_ID],
 [Roll_Number], [Zone_Bylaw_No],[Zone_Schedule_Name])
   
  SELECT
  (geometry), (OP_Designation), (OP_Amendment_No) ,(Zone_Name),(Parcel_ID),
  (Roll_Number), (Zone_Bylaw_No),(Zone_Schedule_Name) 
   FROM inserted
   
   set identity_insert Parcel_History OFF

I think either you are firing your update twice
or the trigger is getting fired twice...

anyways to determine that put the below statement before the insert in the trigger and redo your update

select * from inserted

OR UPDATE(OP_Designation)
OR UPDATE(OP_Amendment_No)
OR UPDATE(Zone_Name)
OR UPDATE(Parcel_ID)
OR UPDATE(Roll_Number)
OR UPDATE(Zone_Bylaw_No)

I was thinking the same thing but no, we are only updating\testing the Zone_Name Field
Changing its value from a1 to a2.
There is also only one peice of geometry that it is attached too. As during testing i am using a blank drawing and inserting on circle( a Table Record) using my GIS Software

I have added
select * from inserted
 to the code and the results are the same. I don't see anything different.
Still stumped!
ITs for sure firing the trigger twice but i'm not sure why!

No, A similar trigger is run on the Roads dataset from the same GIS Program and it works fine. That why i figured it has to have something to do with this code or table set up.

It mean you don't know what and when the program push data and the trigger gets fired.
Maybe you have another trigger in your table or some stored procedures making changes.
Try to find out first adding a time stamp field to your history table...
