hello Geb,
In general, if there are no display or functional errors on your WooCommerce pages these notifications can be dismissed. WooCommerce often updates their plugin and this results in a template version mismatch which generates these notifications, see more info here https://www.styledthemes.com/woocommerce-update-messages-in-your-theme/
we also responded to your support email query please check and if any further questions respond there.
regards
Imre
