Explanation of the screenshots

Here I've created 3 tasks

1. With waiting time not set
2. With waiting time set less than current time.
3. With waiting time more than current time.

The waiting in the filters acts like a toggle
When it is on
Only 1 task is shown i.e. task with waiting time more than current time
When it is off
2 Tasks are shown i.e task in which waiting time is not entered or it is less than current time.
