Do Not Disturb mode glitchy

[jaxsta]

Since the upgrade to lollipop 5.0 i've had to turn "Do Not Disturb" mode on manually every night instead of using the scheduled times as it would not always turn on or off automatically at the pre set times.
Is anyone else having this issue and do you think it'll be fixed in the 5.1 upgrade?
I'm using a telstra phone so 5.1 hasn't been released yet :/

I just got my S5 Monday and I'm on 5.1 and mine works flawlessly as long as it's scheduled. I just miss being able to toggle it on and off by using the volume keys like on my Moto X.
