When adding sub-tasks with estimations, the Estimation field in the Plan and Work mode are not cumulative.
1- Add a Story to back log.
2- Add a Sub Task with 8hrs estimate to that Story
3- Notice that on the Sprint Marker the "Estimate" field is not updated. Same for the Template view on the right side..
- If you open the Story outside of the Rapid Board then the time tracking is cumulative.
- Refer to attachment for a screenshot. The screenshot does not show the Original Estimation for the Sub Task, but it is set to 8hrs.
