How to reduce the time logged for a User Story

[shatarupa som]

I have created a User Story with Estimated Hours (eg: 10h) and while closing the User Story i have enterd the Actual Hours (eg: 10h). Subtasks were already created and closed with Actual and estimated hours (10 h).

After closing the user story with 10h, it is now displaying the Actual effort as 20h (summation of the subtasks hours and the user story hours).

Now, how do i reduce it to 10h?

@shatarupa som - hello! You can delete the duplicate (unwanted) work logs.

Of course, this is if you have permissions to do so.
