An error was found in the previous document and it has been revised and updated in the attached file. I would like to apologize for any inconveniences caused.
This is an old fashion or rather traditional way of writing I understand. In modern English some people even said that \"lease\" and \"Kindly\" shouldn\'t being put together in the same sentence. I\'ve just got used to this writing since I was at school. You could omit either word if you like. Absolutely no harm for that.
