I figured out how to enable sleep mode on my girlfriends 255S but the backlight setting of 5% is not respected. So as soon as we leave the backlight configuration of sleep mode, it goes back to 100%.

I think Garmin's removing the option of 5% backlight and 10% is the minimum.
It still it at 100% no matter what’s set there. There is also no schedule option to turn on sleep mode at a certain time like other watches.
