Performance Task-Libraries

Students are starting their PT. They are not able to access the libraries they created in U7. Is there something I am missing?

@rford For the Create PT, students cannot:
Submit practice performance tasks or any work that has been revised, amended, or corrected by another individual, other than your collaborative partner(s) or cited program code, as a submission for AP Exam scoring.
AP Student Handout page 14.
Since the Libraries students created in Unit 7 have been graded, they cannot be used for the Create PT. Your students can create new libraries for the Create PT.
