Out of stock items problem

Hello, i have tried your plugin to import products from my shopify to woocommerce, all went well except for this:
in my shopify i make all my product’s inventory as “inventory not tracked” so that means i have no stock limit for any product/variant, customers can buy whatever quantity they want. When i imported my products to Woocommerce all the products are shown as out of stock and thus customers can’t buy them. (most of the products have many variants like colors and sizes)
Is there any option where i can specify that products imported to woocommerce to not track the invemtory like shopify, so that i won’t have the out of stock problem?
thanks
