Writing performance reviews for subordinate employees is not something that higher-ups look forward to (it takes their time away from doing their work) and they may not be giving the employee a fair evaluation or explanation of the performance just to get through it.
Have you asked your report why they wrote what the wrote? You may want to have that conversation.
After you have that conversation, ask if you can put a response in your personal file for the record. Some companies allow it and some won't.
