Hello,
WooCommerce 3.3 has some major issues – just check the plugin page, so much so that it isn’t available anymore at this time. You need to downgrade woocommerce to 3.2.6 version.
Once new woocommerce version will be available, we will update our theme within 24 hours.
As with all major revision WooCommerce updates, we advise waiting on a theme update until updating.
Note that before update any plugin you need to be sure that theme and other plugins that you use are compatible with the new version.
Regards
