Problems using _super_attribute_price_corr with configurable products with 2 or more configurable attributes
I need to use configurable products with different prices for each "size" attribute. The problem is that, apart from "size", I have another configurable attribute ("color") which has no influence on product price, but it's need to be configurable.
I'm having problems importing the correct values of "_super_attribute_price_corr" column. This is an example of import array I'm using for the configurable product (before that, all the related simple products are correctly imported):
Array
(
[sku] => 21620320
[_attribute_set] => Default
[_type] => configurable
...
*** (other fields) ***
...
[price] => 219.00
[name] => Name Test Configurable
[_super_products_sku] => Array
(
[0] => 216203203309
[1] => 216203203309
[2] => 216203203315
[3] => 216203203315
)
[_super_attribute_code] => Array
(
[0] => size
[1] => color
[2] => size
[3] => color
)
[_super_attribute_option] => Array
(
[0] => 4A
[1] => Gris
[2] => 10A
[3] => Gris
)
[_super_attribute_price_corr] => Array
(
[0] => 219.00
[1] => ###EMPTY###
[2] => 249.00
[3] => ###EMPTY###
)
)
Everything is imported correctly, except the "_super_attribute_price_corr" association. Only the first "size" appears to have the imported value, and the rest appear to be empty. I attach the admin page image of the example given:

¿Any idea or help with the correct array structure to make this work? Thanks in advance.
