Shipping charged twice on Paypal and not on cart..

hello, we go HikaShop live 2 weeks ago for a friend recommendation. We set up everything and now we are having a proble with shipping. When the customer places an order and selects his shipping preference then goes to check out, since we have paypal it goes to paypal site to continue with the payment and there the shipping looks like a product and there is another shipping charge added to it. We did not set up shipping as a product, we set that up in the shipping module under configuration. Why shipping shows as an Item here if I set this up in the shipping module? why there is another shipping charge added since there is only 1 kind of shipping charge added in the configuration panel in the HikaShop module? Here is what I pasted from Paypal:

The second shipping is added by paypal because of your settings in paypal. You should turn off the shipping handling in your paypal settings:
