Shipping options not showing

Hey Guys,

im struggling a little with the Perch-Shop-Shipping-Options.
I've created a passwordless registration form for my cart checkout. That works pretty well so far. But when i get to my last checkout page including the summary, invoice & shipping addresses the shipping options are empty.

On the registration everything in my Database is added correctly.
A user is created in perch2_members.
A user is created in perch2_shop_customers.
Two addresses (default and shipping) are created for that user in perch2_shop_addresses.

My general shop configuration should also be ok.
The country is active in perch2_shop_countries.
The country is linked to a zone in perch2_shop_shipping_zone_countries.
The shipping zone is active in perch2_shop_shipping_zones.
I got zone related shipping options in perch2_shop_shippings.

But still the perch_shop_shipping_options() show an empty select box. (in default template)

Any suggestions what i am missing?

Thank in advance,
Bastian
