Exactly as the label describes.

I do not understand what the label describes. Is no one ticking the second box, or what am I missing? The second box is greyed out and it's function is redundant, once the first tick box is selected.

Game A has first box ticked.

Game B has both boxes ticked.

My account has previously viewed adult games and confirmed to be 18+. In my settings adult content is enabled.

What is the expected outcome when visiting Game A vs Game B?
