Guild Wars 2

So i’ve noticed something weird on the trading post. exsample 1, i want to sell a mystic dye an there is a buyer asking 6 silver 51 copper. the listing fee is 33 copper so i should get 6 silver 18 copper. however the trading post says i will get 5 silver 86 copper. hmmmm is my maths wrong? so exsample 2, passion flower 3 silver 33 copper. listing fee 17. trading post wants to give me 3 silver 0 copper. If anyone else has noticed a discrepancy please speak up so our voices may be heard
