Wingpanel function switches continuity suggestion / bug

Have noticed that wingpanel switches have slight continuity issues.

When;

Snooze Night Light is ON = **switch to left and grey**, when OFF **switch to right and blue**

Audio is ON = switch to right and blue, when OFF switch to left and grey

Wireless is ON = switch to right and blue, when OFF switch to left and grey

Bluetooth is ON = switch to right and blue, when OFF switch to left and grey

Notifications ON = **switch to left and grey**, when OFF **switch to right and blue**

With notifications, it should be that they are either on to the right and blue or off to the left and grey, but as it is called Do Not Disturb the name gives it a function, but IMO it should be just notifications on or off. rather than DND, so notifications are off when DND is on, rather than the simpler notifications on or off.

Snooze Night Light just seems to be reversed compared to the others
