Mac Zoom Breakout Rooms are collapsed by default

I am a zoom manager for large events. I am a mac user. When I open up breakout rooms, the first 17 rooms are expanded and after that they are all collapsed. I have to go in and individually click on each room to expand it so I can see who is in each room. My friends who are Window users say that all the room are expanded when they open their breakouts. 

As I think about this, it has been this way for years. I'm amazed that I'm not seeing a lot of mac users complaining about this issue.

Thanks.
