No hot air from the middle 2 vents when auto is on

2006 ML500. When auto is on, only 2 side vents have hot air coming out, the middle 2 feel warm, but don't blow any air out. They work fine if I use the manual distribution buttons.

And if I turn the temperature lower, the middle 2 do blow cold air out.

Is this by design or I need to see a dealer?
