how is the DND bug still in nougat?

that Do Not Disturb bug in marshmallow where DND would not turn itself off after an alarm (using the DND until next alarm option) still seems to be present on my 5X with nougat. This was a semi-frequent issue on my Nexus 6 with marshmellow where it would happen once every few weeks and DND wouldnt turn itself off and couldnt be turned off via the quicksettings toggle. Had to set a schedule for 1min from now to get it off. Seems my 5X which ive just recently started using does it seemingly every day, though fortunately, the quick settings toggle works to turn it off, it just doesnt turn itself off like it's supposed to. Slightly less annoying, but annoying nonetheless since it is every weekday. not 100% sure if it started after the sept 6 update or if its always been there. ive only been using the phone a couple weeks. regardless, DND has been annoying me for the better part of a year. when it works, its awesome. :-/
