Translating Comments Plus / Custom Comments Template Addon

I'd like to request a change in the "Custom Comments Template"-Addon. The phrases are already translated in the general WordPress-language file. However the addon refers to the Comments Plus-language file that doesn't include those phrases, e.g.:

printf( _n( 'One Response to %2$s', '%1$s Responses to %2$s', get_comments_number(), TEMPLATE_DOMAIN ),

Could you either add the phrases to the Comments Plus-language file or - preferably - change the code for already existing phrases used by every WordPress installation?

printf( _n( 'One Response to %2$s', '%1$s Responses to %2$s', get_comments_number() ),

Thanks.
