Weight Based Shipping strange behavior

[gsak]

hello forum, 

i have  1.5.4.1 prestashop version installed

 

and i have figure a strange behaviour with the Weight Based Shipping.

 

when i add products to basket everything works well until the weight is under 8 kg when the weight is equal to 8 kg my shipping price from 8euro goes to 200 euro.

 

Do you have any idea what is wrong

Thanks

hi,

 

check your weight range, you've only defined 6-7kg and 8-9kg, so if the weight is between 7-8kg Prestashop cannot calculate the fee. Hope it helps.
