I love the discussion here as to possible reasons why the labeling is different.
That said, there's a very good chance it's just because the initial version had 3, got translated, then someone added a 4th item and it never got translated.
I know someone responsible for these labels and descriptions for a fairly large company, can absolutely confirm this will happen a lot. The product has to go out to the stores and there is just no time to get these translation anymore. I also know of products that shipped to large stores with false information on the label, knowingly because changing it would take too much time and money.
