Solution

Here we will be discussing the Original estimate and Time tracking field on Standard and sub-task issue type.

When a sub-task is associated to a standard issue type (Story/Task) the Time tracked on parent issue will show value from sub-task when Include subtasks is checked.

When we add Original estimate on parent issue, the Time tracking will show time as sum of Subtask as well as Parent issue. Field "Time tracking - Time remaining" is a summation of remaining on the parent + remaining on the Sub-tasks combined. You can refer issue history to view changes made to Remaining Estimate and Original Estimate.

After adding/changing Time remaining on parent issue

If you wish to track the time of the Parent issue without affecting the efforts from the subtask then you need to create a custom time tracking field and map it to the Parent issue type and educate users to log work/track time for the standard/parent issue type using the custom field.
