Variation images not showing up properly

As i am using your ” Aliexpress Dropshipping and Fulfillment for WooCommerce ” plugin and we are getting all products form Ali Express. Somw of our products do not show variation images properly. Can you please have a look and give me suggestion. I tried it by deleting and import again. Please give me a solution.

For example this product:- https://millenniumstuff.com/product/universe-solar-system-bracelet/

Thanks
