Incorrect discounts at Ben's Store (and perhaps also at festivals)

[obsidian marsh]

Are these transposed digits? The discounts and the actual price seem to be mixed up. I also bought something to see if the discount would still be deducted, but you pay full price.
I saw the same thing in the store at a festival. However, I can't remember which one or whether it's a general problem. (PC Version, Steam)

EDIT: Is just checked the animal festival and the shop's discounts are working properly. Therefore, the problem seems to relate exclusively to Ben's Caravan and Ben's Shop at the Winter Market.

I also noticed this in my game! I don't buy from Ben often so I wondered if I was misremembering and he always charged MORE than the normal price since it was 'specialty' items. I haven't done a festival to check if those numbers are transposed yet.

Had the same issue including Ben's stall at the Winter Festival
