Shipping not working after switching language

[greaves]

Hello,

My shop is in two languages.
I have one shipping method (shipping by rules) which affect a price depending on the weight and the country.

It works well if you add your product and the confirm your payment.
The thing is, if you switch the language between the moment you added your product to your cart and the moment you confirm the payment, it goes wrong and say 'We are sorry, no shipment method matches the characteristics of your order.'.

I cannot figure out why it reacts like this.

Any help would be great !

Regards
