Missing 1 letter of applicant name on application confirmation & ds-160 has another state

Hi Everyone.

I have two questions looking for your experiences if faced similar.

  1. I have noticed that middle name 1 letter is missing on the appointment confirmation page for the applicant name and in ds-160 it is correct [having biometric soon], there is no response from support or call not connecting, either not able to update my profile any one faced this and did it pose any problem?
  2. two months back I selected a location X and ds-160 displays this location X and due to some unexpected reasons I was marked no show, again I took an appointment for another location Y and my ds-160 still shows location X, is it really something to worry?

Thank You everyone in advance.
