build folder has extraneous suffix

After using the Upload tool our builds that are actually downloaded by clients have an additional suffix that I cannot understand where it comes from.
Instead of “NameOfGame” inside of the install folder it is downloaded as “NameOfGamer0nXB” instead, starting the game still works but it breaks the macOS build and prevents it from correctly displaying its native app icon when the user starts the game.

Is there some reason why this would happen and how can I prevent it?
