Cannot edit entity properties

I am making a moving saw blade for my first map. I was making it and I made the trigger hurt brush around it. I set the settings to the brush that I needed, but I forgot to name it. So when I tried to double click it just gave the vis-group page and I could not edit the properties.
I tested that it worked in the game, but I had no way to change it. I would have to create a new entity every single time. Also since it is connected to the saw prop and other entities I would have to remake the whole saw if I wanted to change a small property like the entity name or how fast the saw moves.
It has not been like the always and I have no idea how to fix it.

Thank you for your time
