Sarix Enhanced (Maxwell) requires the camera being set to 4:3 aspect ratio in order to utilize the New White Balance. If you set your camera to 16:9, you can still configure White Balance, but it will not work in that mode and you will not get an error indicating that it is not working.

Configuring White Balance only works when your camera is in a 4:3 aspect ratio. If your camera is instead configured for a 16:9 aspect ratio and you try to set White Balance, this feature will not work, but you will not be given any error indicating that it is not working.
Change the camera to a 4:3 aspect ratio to utilize the New White Balance.
