Germanized für WooCommerce + WooLentor

hello everyone, I use “woolentor” together with “woocommerce” and the plugin “Germanized for WooCommerce”. works quite well so far, but on the “checkout” page “select payment method” and “order overview” appear twice and this only disappears after deactivating “woolentor”. so it must be woolentor. other than that, the “buy now” button has disappeared. can someone help me?
