Why do all the BoolValues become true after i only change one of them and rejoin?

So i have a script which makes a few (8) Bool Values inside of a folder which is in the player and its supposed to save those values when edited. And i have a script which determines the functions of a few Remote Events. For some reason when i edit one of the values using a different script only one changes but when i rejoin all of them become true, why is that?

Here is the Save script:

local DataStore = game:GetService("DataStoreService")
local ds1 = DataStore:GetDataStore("NOPE")
local ds2 = DataStore:GetDataStore("NOPEE")
local success, err = pcall(function()

game.Players.PlayerAdded:Connect(function(plr)

        DAFERRAOwned.Value = ds2:GetAsync(plr.UserId, Cars.DAFERRAOwned.Value) --or false


        --game.Players.PlayerRemoving:Connect(function(plr)

And here is the Remote Event script :

end)
--------------------------------------------------------------------------2
game.ReplicatedStorage.DA_Venerra.OnServerEvent:Connect(function(plr)

end)


--------------------------------------------------------------------------4

end)
