Cloner does not copy woocommerce products, pages, all posts and more

Hi,

I did a test run of cloning one of our sites on our staging environment and lots of things were not copied. No products or coupons in woocommerce were copied (in fact nothing but the settings were copied), wordpress pages were not copied, only 5 posts were copied and they were copied 3 times.

I redid the clone with all the plugins disabled and with the twenty fifteen theme but the issues still occur.

Are you able to help? Thank you
