I’m having the same issue on my one site. Funny enough I have two websites running this plug in, and the one website is showing fine. The other website I have to update the product page (without doing any changes), for the tabs to show. I checked my plugin version, woocommerce version and the woocommerce database version which are all on the latest versions. The only differences are the mySQL database version (8.0.35-cll-lve vs 10.3.39-MariaDB-cll-lve) and php versions (7.4.33 vs 8.0.30)
