Print it out, take it to your school administration office and show them what needs to be fixed.

I did this because similar to your situation, I had an inept school faculty member with the IQ of obsidian that didnt know how to even access a pdf file. As long as you do no alter the grades/gpa, there should be no issues for them to stamp their insignia on a fixed transcript due to typo errors.
