The original time estimation of the parent story doesn't sum up for the total time estimations of sub tasks. How to activate this?
example:
Story - A
Sub task - a1 - Original time estimation: 2h
Sub task - a2 - Original time estimation: 1h
After manually entering these time estimations in the sub tasks, why doesn't it get automatically added to the Original time estimation of Story A as 3h? How can I get this done?
