Yoga instructor bug

My Sim character is a part time yoga instructor and does classes from home. Well when she started the class nobody did any yoga and she just stood in the mat. When I tried to select start class again It says she’s already instructing a class. Anyways, she has the yoga instructor icon that remains above her head even after resetting sim. That’s not the worst part though, the Sims that were invited to the class won’t leave her home and they’re staying there rent free. Somebody please help. I play in PS4
