"Please note that the confirmation email from {xxx} is only confirming your morning slot or afternoon slot."hmm I think it's the opposite - from what i understood from the email, your slot selection is for the date and the timing will be assigned to you 48 hours before your interview (as it could be morning or noon)! so don't stress, your date will be the same as the one you chose when you booked the slot but the timing could be either morning or noon. hope this helps!
