Spent time in list view is not the same as in single ticket view
I have a project tracker, with multiple child issues inside. We report the time in the child tickets, and it appears on the project ticket as SPENT TIME. But when using the list view, if I display the SPENT TIME column, everything is 0 (see attached pictures).
I think the SPENT TIME column should show the sum of spent time in child tickets (as it is displayed in single mode view).
