Dear aspirant,

As you have mentioned that you have put the wrong names (father and mother name) and you want to edit it , so you are able to edit only one of these. So, it maybe because of some technical issue but if it is not you can contact nta by mailing them about your problem.

You would surely get help from there but still if it occurs you correct atleast one name and submit the application. If they found any discrepancy they would surely inform you. This is a very minute mistake and you need not worry about this so much.
