Galaxy Book 2 Pro 360 - Can't Set Lock Screen Delay

[toolworker]

My Galaxy Book 2 Pro 360 13" goes to the lock screen after one minute. The power plan is configured to turn the display off after 5 minutes on battery / 10 plugged in, and sleep after 10 / 30 minutes. The Advanced power settings are the same.

I don't see any timing options under Personalization | Lock Screen Settings except for Screen Timeout, which goes to Power & Battery and it has the above settings.

The Power & Battery settings have three power modes: Best power efficiency, Balanced and Best performance. But the Control Panel power plan page has two: Balanced, and SAMSUNG MODE which is selected.

Any suggestions would be welcome.

Balanced and best performance the time out screen can adjust also there's several options in those

I have looked in Lock screen and see no time settings. There's a link Screen timeout that goes to Power & battery. There Screen and sleep is set to 30 minutes for everything (for testing) and power mode is Balanced.

It still goes into lock screen after exactly 1 minute.
