Importing variable products with variations (advanced custom fields)

Hello everyone,

I am trying to import some products via the Import function.
I’m using Advanced Custom Fields and all my products have variations with different prices. To see the correct .csv-syntax, i created a product with a few variations and prices and then filled that out with the rest of the products.

Here is the .csv I’m trying to import

The product however is imported with no variations. The propertiers are there but “use for variations” is unchecked. Therefore all the variations aren’t imported and the product is set as not available.

Thanks for any help
