USDA and packet calories not matching?

I bought some strawberries to go with my porridge this morning. Weighed them out so that I wouldn't go over 100kcal according to the values on the packet. When I put them into my diary using the USDA value, it gave me a calorie value of less than half of what I expected. Does anyone know why this would be? Surely strawberries are strawberries and should be pretty similar. Equally, does anyone know which is likely to be more accurate?

    are you using "per serving" information or per 100 grams per cup or whatever....

    Packet/box/plastic thing holding 400g of strawberries. I took some out, weighed them in grams, then entered the weight into MFP in multiples of 1g. On the packet it states 128kcal per 100g. But the USDA value is 34kcal per 100g. Considering they're just plain, fresh, unprepared strawberries should I just use the USDA data?

    Calories in strawberries are < 50 kcal / 100 g.

    ETA: I've been gorging on them these last days. So fresh, so good.

    the UK seems to think they are 30 kcal/100g, mainly from 6g of sugar.

    The packet sounds wrong, or is telling you a per serving / per pack value - the latter is a good fit 400g @ 32 kcal/100g = 128 kcal
