To Modify the WooCommerce Tab Data including the custom tabs our plugin creates you can use the same filter we use to add these tabs.
woocommerce_product_tabs
An example to use this filter put this code into your functions.php of your child theme:
add_filter( 'woocommerce_product_tabs', 'my_tab_mods', 99, 1); function my_tab_mods($tabs) { var_dump($tabs); return $tabs; }
Used var_dump to get actual used Tabs.
