The Notice of Correction and Modification means that the examiner used to think that there were redundant words in your drawings, so he modified the documents ex officio, but later he thought which part was not redundant words, so he issued the Notice of Correction and Modification, and that part did not need to be modified. Sentences with redundant words before are invalid.
You don't need to do anything now, and you don't need to send any documents. Just pay the fee and wait for the announcement to get the certificate. If in doubt, call the examiner in this book and report the application number.
