Why are their more calories in (UK) Asda spaghetti compared to the (UK) Co-op spaghetti?

I was looking at the calories per 100g of Asda durum wheat spaghetti and Co-op durum wheat spaghetti. Both have the same ingredients, but some reason 100g (uncooked) of the Co-op version is 360 calories whilst 100g (uncooked) of the Asda version is 156 calories. Can anyone explain? I feel like I might be missing something obvious. Thank you!
