When you revert the version of a Place, your Place is reverted to how it was when it was saved. It creates a new Version number rather than showing the original Version.
I have had the same problem, what worked for me is opening the project in studio and then reverting it from there by going to Game Settings, Places, 3 dots of the place you want to revert, Version History and then selecting the version you want to have and opening it and publishing it again from there. (make sure the main game is closed otherwise it wont update because the game is already opened). Tell me if you still have problems.
