Hi admin,
Step 1 : I have a Job with 3 task as : ( export job123.zip for backup )

---

Job 1 ------ Task 1
------ Task 2
------ Task 3

---

Step 2 : I had delete Task 1 & 2 and create a export file ( job3.zip) for only task 3

---

Job 1

------ Task 3

---

Step 3 : Restore Job 1 with job123.zip backup file ( just create step 1 ) and then delete Task 3

---

Job 1 ------ Task 1
------ Task 2

---

Step 4 : Import job3.zip ( chose Update existing ) to Job 1

As logical : Task 3 will add together Task 1&2 on Job 1
But , this clear all Task 1&2 and only had Task 3 exist as Step 2

---

Job 1

------ Task 3

I using version 7.5.0
Plz tell me why ?

Admin, plz

Import with update updates all overwrites all existing objects. If you want to restore old you should delete the whole Job.
