Maximum Brightness problem with iMac 2017

Hi, whenever i wake my iMac Retina 2017 from screen off, the display would automatically turn on with maximum screen brightness, regardless of me ticking the auto-brightness or not in the settings.

As a test...

To find out if it's system wide or user specific, try this...

Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.

Does it work in the new account?
