Removing A Grey Field On Shipping Methods At The Checkout

Hi there,

maybe you know how to NOT show this grey field from the screen under the link below. It is in Polish but basically it shows up on the step 3 at the checkout - Shipping methods - and says something like: "Enter city, state, and click here to update shipping costs". We have our shipping costs fixed for each provider so I'm not sure why it pops up there. I will be very grateful for your help.

Anyone? :)
