Unless I am missing something, in the checkout payment section, the title "Payment Network" is not translatable. (The title of PayPal is translatable.)
Although it is a name that doesn't need to be translated per se, I would prefer to change it to "Payment Network (Sofortüberweisung)" to make clear what payment method it is.

netzkombuese commentedYou can change line 10 in commerce_payment_network.module to define('COMMERCE_PAYMENT_NETWORK_NAME', 'YOUR CUSTOM TITLE'); for workaround.
In line 76 you can also change the info description as you like: $display_title .= t('YOUR CUSTOM TEXT', array('!sofortbanking' => $sofortbanking));
Hope that helps.
