I have watermelon and green apple here and the labels are different yes, not only,
most likely if you look at them close one tubs will be slightly taller than the other,
one says 1170gr and the other 1016gr, but both have 90 servings (1 serving = 2 scoops).
It's normal, different plants or batches probably, slightly different serving dose (in grams),
and most likely different scoop size between the two.
But technically you get the same amount with both, they are the same product
