The first name of the student is listed correctly. If a student has more than one last name, their second last name is shown as the primary one, and their primary last name is shown as a middle name, in their first name spot.
For example, Carlos Zapata Diaz should be "Zapata Diaz, Carlos", but I see "Diaz, Carlos Zapata".
This makes it annoying when entering grades in bulk because I have to go out of the order that is listed in SIS.
