Third Party BANK Letter UK correction by manager

Hi,
I have managed to get third party UK letter along with statment(electronic but each page stamped and sign by the customer care manager).According to Policy guidence and instead of money entered in UK he wrote that xxx person is a GP in Birmingham for 32 years and money is available from his aincome.

The date of the letter on top left corner typed is 13/02/2014

Stamped same 13/02/2014
But he corrcted
On this date:14/02/2014 (4 into 3 with black ball point ,(which he used to sign it)after typing the letter and printing it out,when he read it again)
Would it be any problem?
Should I mention in covering letter anything about it that corrected by manager himself etc.etc.

Any suggestion would be more than helpful as I have to send this document any way but in case if there is any concern and I have to go to court will it be defendable?

Your help will be much appreciated.I hope Ola will not be that busy to answer.
