Name mismatch on appointment conf and DS160 conf/passport



I have a query. I did not put my middle name while creating a profile for scheduling the appointment. Now my appointment confirmation has my first and last name whereas my Ds160/passport had First Middle and Last name. will this create any issues. I called up the US traveldocs  guys and they said that it is upto the discretion of biometrics officer and they cannot correct it now. Has anyone faced this kind of issue recently. i am going at delhi consulate

It should be fine.
