Hello,
Seems you have omitted something in the process of installation.
We recommend to reinstall WordPress, upload our theme, install all the plugins for the theme and check. Next, you can install others plugins one by one checking the issue. If the issue appears, deactivate and delete the plugin which you have installed the last.
One more recommendation please check WooCommerce Status (Dashboard > WooCommerce > Status and make sure all the option meet the WooCommerce requirements. If you see lack of options, contact your host provider.
Finally, you can contact WooCommerce support here https://woocommerce.com/contact-us/
Best Regards
