BPCC4K auto focus area selection

Hi,
on page 23 the manual says: "You can select an alternate auto focus point by tapping on the LCD screen in the area that you want to focus."
Does that mean the rectangle is supposed to jump to the area that I tapped on?
My rectangle always stays in the center, no matter where I tap on.
The auto focus mechanism works; I hear it and see it gets sharper. But I assume my auto focus always looks at the center.
Thank you.
