Hello,

Try to add the below code to the functions.php file in your child theme:

remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_title', 5 );
add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_title', 9 );

Then recheck the issue.

Kind Regards
