Why when I complete a task the task doesn't move down to the completed tasks. It is still in my list, but checked off.
It is annoying because it comes up on my printed list everyday.
please post the exact due date you've used in this task.
Recurring tasks are never deleted from the task list and sub-tasks are deleted once their parent task is completed.
You can force a move to history by holding Shift when clicking on the checkbox, but keep in mind that a recurring task will not be displayed when it should based on its recurrence date.
