Cloner unable to copy woocommerce products

Hi - I'm trying to use the Cloner plugin to copy the site with about 9000 woocommerce products. The cloner run for about 6 minutes and the new site was created, all other pages and posts, menu, etc were copied but none of the products get copied over. I already checked and enabled the Cloner's setting to copy custom post type.

Not sure if it matters, but one thing to note is from my source site, all products were "out of stock" (stock = 0).

Can someone let me know what could be causing this issue?
