Hi
Sethi Sir,
I had the same problem on my medicals and wrote to the CIC sydney, australia and they asked me to use the one with the mistakes but they did tell me that they have made a note of it in their system.
I have applied from NZ and my local visa office is in Sydney, OZ. Do not worry too much, they can fix this easily.
Good wishes to you and your family
Have the DMP make the changes on the IMM 1017.
