Load Game Level on Main Menu?

Yeah the Saving and Loading is working fine the Saver however is not the levels its the main character with a BeginPlay and saves the game.

The 2nd picture is set but it wont work because of the 1st one.

The 1st picture however it has me confused are you saying to create a Cast to the Save Game type? I cant understand it and i never seen that
blue thing before, can a you explain that a bit more?
