Physics file wont export with Live2D Cubism Editor 5.0 Alpha 2

The program won't let me export the physics3.json along with the userdata3.json and cdi3.json.
I can only export without the physics3.json file. But I can not even export the physics file on its own.
No visible error is gevin. It goes through the process but the file never appears.
