Hello,
We don’t rewrite that reviews title so that means it comes from WooCommerce. If we print that function of woocommerce -> $product->get_review_count() – (in their files -> https://prnt.sc/1XJZjcjo9V06 ) it returns zero ( https://prnt.sc/3ysNcqOjeyvV ). So this question should be addressed to WooCommerce plugin author and not for us.
Regards
