No shipping (appointments+ and marketpress)

Hi!
I have installed appointments+ and marketpress (last versions, also wp and all other plugins).

I created products, services, services providers and I set all the staff to work.

But after customers click to pay (checkout page) and they confirm the cart it goes to the shipping page (2 pages: one about confirm the email and another to confirm the cart and shipping address).

I have 'NO SHIPPING' clicked on MarketPress settings (and no country selected).

You can try it here:

Any idea will be appreciated. Really thanks!

Regards,
Albert
