Graduate Plus vs. Direct Graduate Plus loans: what is the difference?

I have just discovered something interesting. u/alh9h, since you had loans around that time as well, perhaps you can take a look?

I think she was issued the wrong type of loan, based on the information that is on the Master Promissory Note (MPN) for the PLUS Loans. She signed a MPN for a William D. Ford Federal Direct Plus Loan. Here is the header from the MPN:

In fact, all 3 of the MPNs are for Direct loans.

Is there any chance that a MPN for this type of loan could still have been a FFEL loan, or does this look like a clerical error from 10 years ago that I just caught now?
