Import of Worklog. Not reflecting efforts in the burndown chart as expected.

[Meena]

We are able to import Epic, Story and Subtask along with Work log for the backdated projects

Burndown chart(remaining time estimate report) and sprint report do not consider the worklog based on the dates mentioned in the import report rather shows one straight line which is not correct.

Any change required in the way of import of worklog, so that the burndown chart is shown correctly for backdated projects(where the sprint creation date is today)
Example: Sprint created on 9th Aug for the completed Sprint between 31st May to 15th June.
