Why SQL server trigger not insert records during insert operation?

I have the below insert, update trigger. Update trigger inserts the records in the "TicketMaster_History" table whenever the update operation happens in "Ticketmaster" table.
But the insert triggers not inserting a record in "TicketMaster_History_New" whenever the new record inserted in in "Ticketmaster" table.
I am using the SQL merge command to update or insert records in the Ticketmaster table.

Below is the trigger created in Ticketmaster table:

ALTER TRIGGER [dbo].[trg_TicketMaster_Update] 
   ON  [dbo].[TicketMaster]
   AFTER UPDATE,INSERT,DELETE
AS 
BEGIN

	-- interfering with SELECT statements.
