Address not submited to PayPal

in the last checkoutstep PayPal doesn´t get the address data.

Oops! An error occurred while processing your payment.

10727 - The field Shipping Address1 is required
10728 - The field Shipping Address City is required
10731 - The field Shipping Address Country is required

I´ve tested yet another theme and without all my plugins. The error stays.
