Help with Data Store?

This data store is supposed to save bool values inside a model called WeaponUpgrades. There are 8 boolValues total, yet this script only seems to be saving two of them. Can anyone help me figure out why?

game.Players.PlayerRemoving:connect(function(Player)
local DataStore = game:GetService("DataStoreService"):GetDataStore(Player.userId.. "Weapons");
local statsStorage = Player:FindFirstChild("WeaponUpgrades"):GetChildren()
for i = 1, #statsStorage do wait()
DataStore:SetAsync(statsStorage[i].Name, statsStorage[i].Value) 
end
end)

game.Players.PlayerAdded:connect(function(Player)
local DataStore = game:GetService("DataStoreService"):GetDataStore(Player.userId.. "Weapons")
Player:WaitForChild("WeaponUpgrades")
wait()
local stats = Player:FindFirstChild("WeaponUpgrades"):GetChildren()
for i = 1, #stats do wait(.1)
stats[i].Value = DataStore:GetAsync(stats[i].Name)
end
end)
