Shipping prices not included in the paypal transaction

[done81]

Hi to all,

 

i have a strange problem on the paypal module ( version 3.8.1 ) installed on my prestashop (1.6.0.6).

 

When the user is redirected to the paypal page, the shipping cost and the total price of the order are correct; Also when the user logon with his paypal account the prices are correct, but when he confirm the transaction he pay only the product price....and the shipping become 0 (but the very strange thing is that this change of the shipping cost sometimes happen and sometimes no).

 

I made some test and a strange thing happen.......sometimes i was redirected to the expresscheckout page and sometimes to the standard page (i attached 2 screenshot, as you can see the product price is 24€ and the shipping 9€)

 

i checked all paypal module configurations and it's all ok.

 

Can anyone help me please?

 

Thanks

Paolo
