WIndows 11 Beta - Night light doesn't turn off at scheduled timings

In Windows 11 Beta, I noticed that night light (the bluelight filter) doesn't actually automatically turn off at the scheduled time. For me, I scheduled it to turn on at 22:00 and turn off at 06:30. However, it only seems to turn on at the scheduled time but doesn't turn off at the scheduled turn off time. Another thing is that when I turn on my computer the next day, night light is still on even after my scheduled turn off time.
