Rectification deed needed or not

I have one property in Bangalore. In my sale deed,it consists of two owner names i.e. mine and my wife. My correct name is "KARANAM PHANI RAJA RAO", mentioned in all my educational certificates + passport.. My wife name is typed correctly on sale deed. But w/o is printed as "K.PanirajRao". My name on sale deed is printed as "K.PANIRAJA RAO", along with correct PAN card number, where "K." is initial and stands for "KARANAM". The name mentioned on my PAN card is K.PHANI RAJA RAO. So, I have registered self "deed of declaration" successfully in same sub registrar office without previous owner's signature. and with correct name "KARANAM PHANI RAJA RAO". But in that deed of declaration, page numbers of sale deed for name correction mentioned are wrong. So, I have below three questions in this regard. 1) As I feel registered self deed of declaration is invalid, so, Please let me know, if I need to go for rectification deed again with previous owner's signature + my signature in same registrar office or different sub registrar office ? 2) If self deed of declaration is valid, then please let me know, if page numbers mentioned wrong is valid or not? 3) If I want to sell my property in future, then can I go with "KARANAM PHANI RAJA RAO alias K.PANIRAJA RAO" without going for rectification deed with previous owner's signature ?
