OrderedDataStore isn't working for a global leaderboard in my game, why?

I read the wiki page and I did what I understood but it is still not working and I dont know why, it doesn't even print the Name, Strength, And Place When It Is Told To.

Script:

local ds = game:GetService("DataStoreService"):GetDataStore("UserData")
local ods = game:GetService("DataStoreService"):GetOrderedDataStore("GameData")
local Misc = game:GetService("ReplicatedStorage").Misc
local Number = Misc.Number
local StrengthBoard = workspace.StrengthBoard
local StrengthSg = StrengthBoard.Part.sg
local SHolder = StrengthSg.Holder

function UpdateStrengthBoard()
    local isAscending = false
    local pageSize = 10
    local pages = ods:GetSortedAsync(isAscending, pageSize)
    local topTen = pages:GetCurrentPage()
    for rank, data in ipairs(topTen) do
        print("Rank: ".. rank)
        print("Name: "..string.sub(data.key,9))
        print("Value: "..data.value)
        local name = string.sub(data.key,9)
        local Strength = data.value
        local NClone = Number:Clone()
        NClone.PlayerName.Text = name
        NClone.PlayerStrength = Strength
        if #SHolder:GetChildren() > 0 then
            local LastPlace = nil
            for i,v in pairs(SHolder:GetChildren()) do
                if i == #SHolder:GetChildren() then
                    LastPlace = v
                end
            end
            local X = LastPlace.Position.X
            local RealX = (X+100)+(5*#SHolder:GetChildren())
            local RealPos = UDim2.new(RealX,0,0)
            NClone.Parent = SHolder
            NClone.Position = RealPos
        else
            NClone.Parent = SHolder
        end
    end
end

game.Players.PlayerAdded:Connect(function(plr)
    local leaderstats = Instance.new("Folder", plr)
    leaderstats.Name = "leaderstats"

    local Strength = Instance.new("NumberValue", leaderstats)
    Strength.Name = "Strength"

    local Rebirths = Instance.new("NumberValue", leaderstats)
    Rebirths.Name = "Rebirths"

    local key = "plr-".. plr.userId
    local SavedData = ds:GetAsync(key)
    local SKey = "Strength-"..plr.Name

    if SavedData then
        Strength.Value = SavedData[1]
        Rebirths.Value = SavedData[2]
    else
        local DataToSave = {Strength.Value, Rebirths.Value}
        ds:SetAsync(key, DataToSave)
        ods:SetAsync(SKey,Strength.Value)
    end
end)

game.Players.PlayerRemoving:Connect(function(plr)
    local key = "plr-".. plr.userId
    local DataToSave = {plr.leaderstats.Strength.Value, plr.leaderstats.Rebirths.Value}
    ds:SetAsync(key, DataToSave)
end)

wait(2)

UpdateStrengthBoard()

while wait(60) do
    UpdateStrengthBoard()
end
