The estimates for the stories are not shown in the Backlog view

[Maria Konareva]

We have a story which contains a lot of subtasks. Each of subtask has an estimate so that the estimate for the story should be a sum of estimates for the subtasks. The estimates for the stories are not shown in the Backlog. Is there a way to resolve this? 

On the project settings: 

Estimation Statistic is "Original time estimate" and Time Tracking is "Remaining Estimate and Time Spent"

Estimates on sub-tasks do not appear in the backlog, because they're not of any use there.
