ProfileService Dictionnaries doesn't work?

If I make a dictionary inside the saveStructure the “profile.Data” doesn’t allow me to call it for any reason and says that its nil:

local saveStructure = {

	Wins = 0;
	Losses = 0;
	WolfCoins = 0;
	Exp = 0;
	Spins = 1;
	["3D Skins"] = {

		["Werewolf_Skins"] = {
			["Werewolf_Werewolf"] = true;
			["Black_Werewolf"] = false;
			["White_Werewolf"] = false;
		};

	};
	
}

I don’t know what is really happening here, so I’d be grateful if you can give me a hand with this! :grin:. Hope you have a great day and life!
