Organization members taking down other members

I'm an education user. We have 20 staff members as teachers and each individual login is connected to their individual class. Even though they don't have any connections or co-host my school's class meetings. When a member enters his class, the zoom releases a response that he is already connected to another meeting if he wants to end the meeting he is currently in to join this other one that he needs to teach the class. When he clicks YES it drops another meeting with all students and the member who is the teacher of another class is also dropped. Even if none of the two are registered in the same classes. To each his own specifies this error occurs.
