I had the same issue and running “Clear Template Cache” and clearing WooCommerce Transients didn’t resolve the issue. When you load the Status page, an API call that fetches the system status is called and the template information is included in this data.
To expedite this call, WC stores template data in a _transient_wc_system_status_theme_info row in the options table. For some reason, clearing WC transients didn’t clear this value. However, by removing this row (or simply waiting a bit until _transient_timeout_wc_system_status_theme_info expires), the theme data was updated.
See: WC_REST_System_Status_V2_Controller::get_theme_info, first line for where the transient is called.
