Balachandar, the correction slip for NEET UG 2020 contains both the old detail/ upload as well as the new and corrected detail/ upload. That is why you can find both the old and new uploaded images in the correction slip.

You need not worry as this is the correct format. You will find a note which says '(Changed by candidate)' in red beside the field which you have corrected, i.e. the specific image in your case.
