Custom Input Manager Menu Reset Keybinds

I was Wondering if anyone could help me out with getting my Input Manager to reset to the default keybind when i click a button in the scene this is what i have current

the main reason i need to set this up is because for what ever reason i can not set mouse 0,1 or either of the shifts in the game and i am not sure why

     }
 
 }   

this is my gameManager where everything is set the ResetDefault currently just locks me out of the game
