Empty cart keeps shipping amount

[restodo]

Hi,

I'm on VM 2.6.0 and I'm using Standard Shipping plugin.

For example I have:

Shipment 1 cost  USD 38
Shipment 2 cost  USD 45
Shipment 3 cost  USD 100

If I remove the products from my cart and one of the shipments was selected, when the site say that my cart is empty the amount it isn't.

If I choose for example Shipment 2, USD 45 will be added to my cart.
When I remove the products in cart, the amount in cart stills USD 45.


Could you tell me where can I check to tell the code to clear Shipment Plugin?


Regards.
