Any Delhi University Student admitted to SFSU?

Hi, I am Avneet Kaur Ahuja. I got admitted to SFSU for MSBA Fall 2022. I am working on submitting the required documents as per the SFSU Graduate Division.
The SFSU Graduates studies division has received my official sealed "consolidated Mark of transcripts" from Delhi University. Now, they want I should submit the individual mark sheets and degree certificate in a DU sealed envelope. I don't get what to do for this step and how to apply with DU for the same? Is there anyone from Delhi University? Have you done this step? #masters
