I could view the subtasks below the parent task with a list by now,but
I can only view subtask in the Parent card's right now.What happened?
eg.
<By now>
TODO Doing Done
card-1 card-2
Parent
child-1 child-2
child-3 child-4
child-5
card-3 card-4
<Now>
TODO Doing Done
card-1 card-2
Parent
card-3 card-4
