Problem:
I'm creating custom product tabs with the plugin "Custom Product Tabs for WooCommerce" but the translation content in the tabs is copied to the translation product page. Solution:
Go to WPML > Settings > Custom Fields Translation > Search for the field "yikes_woo_products_tabs" and set the preference to Translate. Relevant Documentation: https://wpml.org/documentation/getting-started-guide/translating-custom-fields/
