Save script not saving?

When someone resets, the stats save and load. But when someone rejoins, it just comes up as blank. There's no output, so I don't know what's going on. Can someone help?

local Stats = {
    ["Swordsmanship"] = 0,
    ["Cooking"] = 0,
    ["Blacksmithing"] = 0,
    ["Woodcutting"] = 0,
    ["Mining"] = 0,
    ["Beast Taming"] = 0,
    ["Foraging"] = 0,
    ["Alchemy"] = 0,
    ["Detection Skill"] = 0,
    ["Farming"] = 0,
}

local SwordStats = {
    ["Short Blades"] = 0,
    ["Long Blades"] = 0,
    ["Great Blades"] = 0,
    ["Axes"] = 0,
    ["Rapiers"] = 0,
    ["Hammers"] = 0,
    ["Katanas"] = 0,
    ["Spears"] = 0,
}

local Plr = game:GetService("Players"):GetChildren()

local StatsDirectory = Plr.Stats
local SwordStatsDirectory = Plr.SwordStats

repeat wait() until SwordStatsDirectory
repeat wait() until StatsDirectory

function saveStats()
    for _, v in pairs(StatsDirectory:GetChildren()) do
        Plr:SaveNumber(v.Name,v.Value)
    end
    for _, v in pairs(SwordStatsDirectory:GetChildren()) do
        Plr:SaveNumber(v.Name,v.Value)
    end
end

function updateStats()
    for _, v in pairs(StatsDirectory:GetChildren()) do
        Stats[v.Name] = v.Value
    end
end

function updateSwordStats()
    for _, v in pairs(SwordStatsDirectory:GetChildren()) do
        SwordStats[v.Name] = v.Value
    end
end

function loadData()
    for _, v in pairs(StatsDirectory:GetChildren()) do
        v.Value = Plr:LoadNumber(v.Name) or 0
        updateStats()
    end
    for _, v in pairs(SwordStatsDirectory:GetChildren()) do
        v.Value = Plr:LoadNumber(v.Name) or 0
        updateSwordStats()
    end
end

for _, v in pairs(StatsDirectory:GetChildren()) do
    v.Changed:connect(function()
        updateStats()
    end)
end

for _, v in pairs(SwordStatsDirectory:GetChildren()) do
    v.Changed:connect(function()
        updateSwordStats()
    end)
end

This is in ServerScriptService if that helps.
