Hii!
Generally, it doesn't cause you too much problem, but if you apply for a reserved category and fail to present the proof, you are considered a general category candidate. You haven't mentioned or tagged the name of the exam fir which you have asked the question. But, I would suggest, not to withdraw the application and make corrections if possible, when the date comes.
Hope this helps.
Good luck!
