Hi aspirant,

See this is a very minor issue and should not cause problems as there are certain ways to write the abbreviation for Mohammad. However it may cause some hinderence as there would be no proof that both the persons in documents are same or not. In that case you should also carry your parents document which would be same on both the documents. Also to add some more cushion you can carry an affidavit claiming that both the persons are same supported by your parents document.

Hope it helps!!
