Canvas/PowerSchool nightly sync putting students in multiple sections

Community Member

We are having an issue with our nightly rollover from PowerSchool to Canvas. Earlier in the school year, there were some changes made to student schedules in PowerSchool where students were moved from one section to a different section for the same teacher. Those changes reflected in Canvas accurately. Since the new year began, many of those students who had schedule changes are now showing up as members of both sections in Canvas. I removed the section that was showing up incorrectly from each individual student's Canvas accounts, just for the nightly sync to hit and the sections to reappear. 

We started off looking into whether things were done correctly in PowerSchool, which our PowerSchool administrator looked into and said all changes were made by the book. 

Is there a setting I am unaware of or is this some kind of larger issue?
