Main Menu 3D Asset

Quick question for anyone who has the main menu 3d asset from the marketplace, I am trying to add variables to save and load for example a gold variable and while the value of the gold variable works perfect when clicking on exit to main menu, unfortunately it resets to the default value when clicking on exit to desktop. I did watch the tutorial video and submitted a question in the main menu 3d section with the marketplace however it has been almost 41 hours now and I have not received a response from the developer. Does anyone else have this asset and if so what did you need to add so the value of the variable in this case gold stays what it should be when clicking on exit to desktop? Again when I click on exit to main menu the value stays like it should it’s just when I click on exit to desktop it’s when it resets back to the default.

Thanks
