table.insert resets some values to 0?

For some reason when I try to insert data into a table using table.insert, the x,y, and z positions get reset to 0. I have checked the values for x, y, and z outside of the table.insert, and they seem to work, but in the table, the values return as 0.

the defective part:

for i, obj in ipairs(plot.itemHolder:GetChildren()) do
            table.insert(data, {
                ["name"] = obj.Name,
                ["transform"] = {
                    ["x"] = obj.PrimaryPart.CFrame.X;
                    ["y"] = obj.PrimaryPart.CFrame.Y;
                    ["z"] = obj.PrimaryPart.CFrame.Z;
                    ["r"] = obj.PrimaryPart.Orientation.Y
                }
            })

        end

the whole code:

local players = game:GetService("Players")
local replicatedStorage = game:GetService("ReplicatedStorage")

local plotManager = require(script.Parent.ServerModules.PlotManager)
local dataStoreService = game:GetService("DataStoreService")
local dataStore = dataStoreService:GetDataStore("Bleep")

local tries = 3
local dataloaded = false

local function set(plr)
    if dataloaded then
        local plot = plotManager.returnPlot(workspace.plots, plr)

        local key = plr.UserId
        local count = 0

        local data = {}

        for i, obj in ipairs(plot.itemHolder:GetChildren()) do
            table.insert(data, {
                ["name"] = obj.Name,
                ["transform"] = {
                    ["x"] = obj.PrimaryPart.CFrame.X;
                    ["y"] = obj.PrimaryPart.CFrame.Y;
                    ["z"] = obj.PrimaryPart.CFrame.Z;
                    ["r"] = obj.PrimaryPart.Orientation.Y
                }
            })

        end

        print(data)

        local success, err

        repeat
            success, err = pcall(function()
                dataStore:SetAsync(key, data)
            end)

            count = count + 1
        until count >= tries or success

        if not success then
            warn("Data could not be set." .. tostring(err))

            return
        end
    else

            if loadedModel then
                loadedModel:SetPrimaryPartCFrame(CFrame.new(saved.transform.X, saved.transform.Y, saved.transform.Z)*CFrame.Angles(0, math.rad(saved.transform.r), 0))

                loadedModel.Parent = plot.itemHolder
            else
                return
            end

        return {}
    end
end

local function unloadTycoonData(plr)
