Timespent 0 in main task when is > 0 in sub tasks

Hi,

I have a problem when I try to view my tasks in a project. I include tasks in the proposal and in the project I have the same tasks. If I want to create a new task from the main task, the main task has a value in the PlannedWorkload columns, subtasks not and subtasks has a value in TimeSpent column but main task have 0 instead of the sum. So, I have to make the sum manually to be sure hours are ok. Could I select or change something to make main tasks sum?
