FP3 App Schedule Problems

I have set the Bedtime mode and Do Not Disturb mode on my phone to come on at specific times (22:00 - 5:00). Bedtime activates ok (turns screen grey) at 22:00 but deactivates itself at 00:00 and doesn’t come back on.
Do Not disturb turns on but doesn’t turn itself off automatically and annoyingly even when I hit the icon and it indicates that it is off my calls still seem to be muted until I adjust the setting manually using the volume keys.
