Ignore the "Maximum Points Available" - even if this is set with a number, no grade will be created in Moodle for the PeerMark assignment. If you want to grade this work, you would need to [create a manual grade item](https://ncsu.service-now.com/delta?id=kb_article_ml&sysparm_article=KB0021219) in Moodle and then enter the grades for each student.
