Shipping method changes after adding an address

-- HikaShop version -- : 2.2.2
-- Joomla version -- : 3.2.0
-- PHP version -- : ?
-- Browser(s) name and version -- : Firefox 25 (mac)
-- Error-message(debug-mod must be tuned on) -- : Error_message

During checkout I have two shipping methods:
1. Sent (Costs involved)
2. Pickup (Free)

For picking up the goods no costs are involved. But when selecting pickup and further on in the process I'm adding an address the process adds shipping costs. How can I change this.

greetings,
Richard

To make things more clear an overview of the process:

Hi Richard,
Your issue is probably coming from the way you configured your shipping methods, so can you show me how did you configured you two shipping methods through some screenshots ?

Attached my different shipping methods.

Hi,
What I wanted to see was your shipping methods restrictions, can you also show me some screenshots of the problem that you are through your checkout process and give me a link to your shop so that I can test it myself ?
Thanks.

Hopefully this will do the trick.

Any suggestions?

Note that through your checkout workflow ("Hikashop->System->Configuration->Checkout") your "shipping" action will change regarding your address/user account, so be sure that your the login/address action before or in the same step as your "address" action.
