Shopify variation products showing on wordpress as a 0 stock limit of products

Hi, I’m using your app. But I’m getting an error when I’m importing products. The variation products showing on my WordPress website with 0 stock limit. That is why customers can not purchase those products. SO please tell me what’s the solution for that?

This product is available on the live site but when I’m choosing the variations it’s showing me “out of stock”
