Plugin Import WP PRO update function does not update

Goodnight

The update function does not work, as it does not update the data, especially the body of the product description and price. Because the important factor of products are product updates. But I inform you that the same plugin in question appeared in the price and description update preview.

I use the following plugins:

Import WP 2.9.1.

Import WP PRO 2.6.1

Import WP WooCommerce Importer Addon 2.1.1.

Thank you for the solution to this problem. Thanks
