POS Task List PDFs are being generated with duplicated tasks

When the settings-state-school-tasklists setting is set to Unaligned and you generate a POS Task List PDF for a student, it is showing all of the State tasks first, which is correct, and then showing all of the School tasks again, despite them being aligned with the state task list. It should only be appending tasks from the school task list that are not aligned to the state task list.
