Missing middle name on appointment confirmation page

My Ds-160 had applicant name as per passport, which is Last Name, First Name Middle Name. But my dropbox appointment confirmation has it as First Name Last Name.

I can’t change it on my profile in new visa scheduling site as this is how it was filled while creating since only first and last name was asked.
I have dropbox appointment at Chennai and planning to drop documents to Mumabi/Hyderabad.

Will the missing middle name on appointment confirmation page create any issue while dropping the documents?
In such cases will the VAC office be able to update my name to add middle name in it?

Middle name should not be an issue. Don’t worry.
