Nuki SL 4.0 nightmode is not on time

Nightmode on my nuki SL 4.0 is set to start at 0:00 but it doesn’t it will be between 1:00 till 5:00, every day it’s a suprise.
My first one you knew when you heard your lock it was 0:00 but now it’s al over the place.

Battery saving on the app is off incase this is a problem and the time on the log is on time.

Is this a bug? Anyone else this problem?
