Hi everyone, I need help. I keep trying to sort my items on the front page and they don't sort.

I go to categories / Other layout options / most recent by date first.

But the items do not sort. they just stay at oldest first.

Versions:
K2: v2.6.9
J: 3.4.4
site: greenvalleychristianchurch.com scroll down to bottom of page to see blog items but they don't show the newest item first.
