Hello,
As I already indicated you the plugin caused the issue on your site in my last message and it was (Woocommerce Multilingual plugin), that plugin conflicts with the styling of woocommerce product tabs, I just deactivated it and the issue resolved.
So please now contact WPML support and ask WPML support to solve the issue for you as it is fully compatible with WoodMart WordPress Theme so it has to work with the Theme without any problem, Its the plugin issue.
Best Regards.
