Having troubles saving dictionary using datastore2?

Can someone tell me why this isn't working? All it's doing is storing values from a table, the non table ones work but for some reason this doesn't save with no errors

game.Players.PlayerAdded:Connect(function(player)
    local playerMana = DataStore2("Mana", player)
    local playerSouls = DataStore2("Souls", player)
    local playerRebirths = DataStore2("Rebirths", player)
    local playerAttacks = DataStore2("Attacks", player)

    local attacks = {
        ["Smash"] = true,
        ["Fireball"] = false,
        ["Blast"] = false
    }

    local statsFolder = Instance.new("Folder", player)
    statsFolder.Name = "Data"

    local attacksFolder = Instance.new("Folder", player)
    attacksFolder.Name = "Attacks"

    local mana = Instance.new("NumberValue", statsFolder)
    local souls = Instance.new("NumberValue", statsFolder)
    local rebirths = Instance.new("NumberValue", statsFolder)

    --Attack values
    local smash = Instance.new("BoolValue", attacksFolder)
    local fireball = Instance.new("BoolValue", attacksFolder)
    local blast = Instance.new("BoolValue", attacksFolder)

    mana.Name = "Mana"
    souls.Name = "Souls"
    rebirths.Name = "Rebirths"

    --Attack names
    smash.Name = "Smash"
    fireball.Name = "Fireball"
    blast.Name = "Blast"

    local getMana = playerMana:Get()
    local getSouls = playerSouls:Get()
    local getRebirths = playerRebirths:Get()
    local getAttacks = playerAttacks:Get()

    --Load

    if getMana ~= nil then
        mana.Value = getMana
    else
        mana.Value = 0
    end

    if getSouls ~= nil then
        souls.Value = getSouls
    else
        souls.Value = 0
    end

    if getRebirths ~= nil then
        rebirths.Value = getRebirths
    else
        rebirths.Value = 0
    end

    if getAttacks ~= nil then
        for i, v in pairs(player.Attacks:GetChildren()) do
            v.Value = getAttacks[v.Name]
        end
    else
        for i, v in pairs(player.Attacks:GetChildren()) do
            v.Value = attacks[v.Name]
        end
    end

    --Save
    mana.Changed:Connect(function()
        playerMana:Set(mana.Value)
    end)

    souls.Changed:Connect(function()
        playerSouls:Set(mana.Value)
    end)

    rebirths.Changed:Connect(function()
        playerRebirths:Set(mana.Value)
    end)

    smash.Changed:Connect(function()
        playerAttacks:Set("Smash", smash.Value)
    end)

    fireball.Changed:Connect(function()
        playerAttacks:Set("Fireball", fireball.Value)
    end)

    blast.Changed:Connect(function()
        playerAttacks:Set("Blast", blast.Value)
    end)
end)

The other values save, the dictionary does not.
