Swords and Shovels course, game manager bug

Hello,

Thanks for reading my post. I am working my way through the Swords and Shovels course and am developing the game manager. I have encountered a bug where when I pause the game and press the restart button, I have to press the pause button again and it does restart the game. BUT, Unity does not unload the level as in the videos. Instead it reloads the main level instead of going back to the boot scene. This results in everything clearly being duplicated on my screen. I was wondering if by luck anyone else is working through the course, or had already worked through it and encountered the same bug. I am currently combing through the code and it appears that I have typed all of the code as indicated in the course.
