ChangePlan table

Experts,

We are upgrading to HP SM v9.41 hybrid.

The change module is on process designer now.

While testing , i have noticed that , in the change workflow, when an auto task is getting added, it gets added into the 'changePlan' table also. 

Could some one tell me, how do we get to make the active flag in the changePlan to false ?

Also, is there a process or ruleset which I should be calling inorder to close the change task properly.

Attaching the screenshots of

1) cm3t workflow

2) changePlan table.

thx
