You appear to have two 'sleep' entries and one 'wake'.
This happens occasionally and usually causes the problem you are seeing.
I suggest you delete all three and then use the humax on screen menu to (settings, preferences, timer option) set them up again.
EDIT: you may get away with just fleeting the 04:45 sleep timer as this looks like the anomoly.
Rather than setting a timer on / timer off, it is safer to schedule a daily 'reminder' as this will have the same effect without causing your problem when half of the 'pair' gets deleted. e.g. Menu >> Guide >> New Reservation >> Mode = Reminder
There are two possible states that display the 'blue ring' in standby, one is the unit not going into standby but remaining in a 'half-awake' state, the other is when the unit does enter standby state correctly, BUT the ring remains blue due to redring leaving leaving the LEDs in the wrong state. I think you probably encountered the second one. You can check which of the 3 states your Humax is in by looking at the list HERE
