To reproduce: load the defaults then click the 8:00am plus button Once: you might expect restful sleep after 5am Twice: you might expect restful sleep after 6am Three: you might expect restful sleep after 12am But 12am (midnight) is before 5am :-), so I assume it overflowed, or it means 12pm (the following day).
