Shipping cost is not including in paypal express checkout in wordpress woocommerce

I brought http://www.woothemes.com/products/paypal-express/ plugin for my wordpress site running woocommerce. But the shipping cost is not including during paypal express checkout.

I checked all setting in woocommerce shipping. I also checked other payment gateways they are including shipping cost

Can anyone please suggest how to include shipping cost in paypal express checkout for woocommerce.
