Issue with displaying people in Episode 2 (Life is Strange)

I want to ask for help in solving one problem: in the second episode in the scene in college, I did not show the people in Jefferson's class. There is no way to work around this problem to continue playing. The scene when Max enters the classroom for Jefferson's lesson, two girls are taking pictures (I only have cameras in the air), one girl is standing by the window, and two are sitting on Max's desk (there is no girl or two guys). Help me please :(
