I recently found out that FireBase resets the project bucket to the name of the project by default if you save a new name or sometimes if you close or open the project.
This really messed me up as the Project was reading fine one time and the next, it didn't. I'm not using the project bucket designation.
The solution was to set the Project Bucket to " " (a blank text entry) on the initialize screen command. This way each time the screen is run, it will override the project bucket reset.
I think this is a bug and should be addressed in a future update.
