"Some settling may occur."
That excuse may be valid for cereals and other bulk-packaged groceries, but not for individually wrapped portions like these granola bars.
There's no deception in the labeling of the package, which did, as advertised, contain six pouches of two 1.5 oz bars each, but the package is inappropriately large. The most common explanation would be that Target subjected their product to a "grocery shrink ray." Alternatively it may be that the product used to be sold in boxes of eight, or that a surplus of unlabled boxes of that size were available and were used rather than discarded. We'll see if the package shrinks with time.
Addendum: Reader mehughes124 provides the explanation in his comment.
