Avatar Scaling / data store not working?

Today I was testing my project and I was adding saving player scale. I did a testing server with a few friends and I noticed when they reset, died or left and rejoined, their size would increase dramatically. I’m not sure what is causing this issue, I’ve looked into it and can’t find anything that would increase the size with-out a player activating the tool or the script changing the scale by force.

If you can help then I would appreciate it! Also include what I'm doing wrong.

DataStore script:

local Data = game:GetService("DataStoreService"):GetDataStore("I")

game:GetService("Players").PlayerAdded:Connect(function(Plr)

    --  // Leaderstats

    local Stats = Instance.new("Folder", Plr)
    Stats.Name = "leaderstats"

    local Strength = Instance.new("IntValue", Stats)
    Strength.Name = "Strength"  

    local Rebirths = Instance.new("IntValue", Stats)
    Rebirths.Name = "Rebirths"

    -- // Alt values

    local Scales = Instance.new("Folder", Plr)
    Scales.Name = "Scales"

    local BWS = Instance.new("NumberValue", Scales)
    BWS.Name = "BWS"    

    local BHS = Instance.new("NumberValue", Scales)
    BHS.Name = "BHS"

    local BDS = Instance.new("NumberValue", Scales)
    BDS.Name = "BDS"

    -- // Loading stuff

    local Data1 = Data:GetAsync(Plr.UserId)

    if Data1 then
        for i, v in pairs(Stats:GetChildren()) do
            v.Value = Data1[v.Name]
        end
        for i, v in pairs(Scales:GetChildren()) do
            v.Value = Data1[v.Name]
        end
        print(Plr.Name .. "'s data loaded successfully!")
    end

    -- // Saving stuff

    spawn(function()

                    SaveData[v.Name] = v.Value
                end

                for i, v in pairs(Scales:GetChildren()) do
                   SaveData[v.Name] = v.Value
                end

                Data:SetAsync(Plr.UserId, SaveData)
