Hi,
Check your shipping settings: Make sure that you have set up your shipping options correctly in your WordPress dashboard. Go to WooCommerce > Settings > Shipping.
Update your theme and plugins: Make sure that you have the latest version of the WoodMart theme and any plugins you are using.
Deactivate all the 3rd party plugins and activate only theme-required plugins on the site and then check the issue. If the issue remains then provide us the WP-ADMIN Login details of your Site in the Private Content field along with the permission to completely debug your Site which includes deactivating all the third party Plugins and removal of on-Site Customization changes too, so that we can thoroughly check this issue on your Site and assist you accordingly.
Best Regards.
