If I have sub-Tasks, the progress is shown in the Main-Task.
If I make any change (e.g. set the due date) the sub-Task gets a green checked icon and the progress shows that the sub-task is done. But it is not correct, since the sub-task is still open.
What is the source for the progress of sub-tasks? How can I change a sub-task in order to remove it from the progress because it is not done yet?
