The country order is not correct. As the countries like France, Germany, China, Austria are only for PhD not for MS/Mphill leading to PhD. The best option for you is Hanyang, AIT, Turkey etc. i think you cannot edit your form. Ask from HEC person that how you can edit. I think you cannot edit. HEC will place you at the university where they have less applications and also good related to your education. You may write hand written application by telling the mistake you have committed. see this link.
