In reply to Joel.

I suspect that we cannot determine whether either product has more oatmeal or apples than the other. Monkfruit sweetener is (gram for gram) much sweeter than sugar, so I can believe that if they left all of the other ingredients the same, the low-sugar version would naturally weigh less.

Although clearly the order of cinnamon and "natural flavors" is different, so there must be some differences other than just the sweeteners used.
