When I create a configurable product through Products > Catalog > Add Product, everything works well. During the process of creating this product I add 3 configurations and these virtual products are created and linked to the configured product.
The configurable product is visible in the front-end and there are 3 options available. However, when I do an export, delete all products and re-import my products; the products are imported, but the configurable product does not have any visible relation with the virtual products. Also, the cnfigurable product is not visible in the front-end (store).
The import file can be viewed in this PasteBin.
