How to save data stored in game instance?

Check out this project of mine: [FREE PROJECT] Physics Driven Spacecraft - World Creation - Unreal Engine Forums

It has exactly the same audio setup that uses a savegame BP, a game instance and widget sliders.

Hey guys Ive searched high and low and im still scratching my head. So basically i have audio sliders that cast to my game instance and thus are read and keep position after closing the widget. But of course they reset upon game reload. I wish to save the slider positions with a save file. However ive tried but it doesn’t seem to work. Any help pretty please with a couple of cherry’s thrown in for good measure!

This is the game instance BP
