Update button does not appear

Describe the bug
After open a preview, there is no option for me to update the game scene. As you can see, the Preview button is still the same, and it only open another preview screen.
I’ve restart my Mac, uninstall and re install the app, but nothing has change.
Looking for a solution asap, working without update option is too frustrating.
