Contrast

I have CorlDraw 2019 and I am in CorelPhoto Paint.

I go to Adjust then Brightness/Contrast/Intensity.

I Window Opens for all 3. of these.

I Click Reset to Set them all back to 0. and this is what I need help with?

If I move the Brightness Slider Up the Image gets Brighter.

And if I move the Brightness Slider Down the Images gets Darker.

Not if I move the Contrast Slider Up the Image gets Darker.

And if I move the Contrast Slider Down the Image gets Gray or Dark Light.

So if I move the Contrast Slider Up and it makes the Image Darker how is this Adjusting the Contrast?

Contrast is the Brightest Bright and Darkest Dark.

So as I move the Contrast Up the Image gets Darker.

Or am I not Understanding how it works?
