Import configurable products through data profiles

Question

I have imported a configurable product through data profile for different stores view. For the model I exported one configurable product and edited it by adding separated lines for each store view. The products are imported almost fine.

I don't understand why I can't see configurable attributes for my product in frontend. When I try to edit the configurable product in admin it shows me

Only attributes with scope "Global", input type "Dropdown" and Use To Create Configurable Product "Yes" are available.

and I can choose some attributes like color and size. I will mention that my attributes have Scope - Global and Catalog Input Type is Dropdown.

My question is what have I done wrong? If I check my attributes than my product will be fine on frontend but I don't think this is the solution
