Why does this only work locally and not server sided?

I got this datastore script working fine, it saves everyone's stats and everything i have in the table but the "Stats" table i got in there only saves in the local side of roblox so when you click play in studio.

I'm saving a table and putting that table into another module so local scripts can read it and get information from it, that might be the problem i don't know.

In the server script i'm setting ClientStatCache table to ClientStatCache[player] so i know which players have which stats and i'm adding the table i'm saving in the datastore script into that module table.

Like i said it works in studio but not in game, it might have something to do with the localscript grabbing the player table from the module cause it dosen't seem to exist. It prints nil when i print ClientStatCache[player].

I'm not getting any errors.

Datastore module script:

function SetupPlayerData(player)        
    local success, data = LoadData(player)

    local function ReturnOwned()
        for i,v in pairs(ToolData) do

        end
    end
    ReturnOwned()

    if not success then
        PlayerData[player] = false
    else
        if not data then
            print("Save not found, creating a new save!")
            PlayerData[player] = {
                Cash = 0,
                Level = 1,
                Experience = 0,
                Rebirth = 0,
                Rank = "Beginner",
                Tool = "Trident",
                Backpack = "Backpack1",
                BackpackAmount = 0,
                Stats = {
                    Quests = {
                        Active = {},
                        Completed = {},
                    },
                    Totals = {
                        Souls = {
                            ["Bob's Adventure"] = {
                                Harvested = 0,
                            },
                            All = 0,
                        }
                    }
                }
            }
            savePlayerData(player)
        else
            PlayerData[player] = data
        end
    end
end

Server script:

local ClientStatCache = require(game.ReplicatedStorage.ClientStatCache)

ClientStatCache[player] = {}
table.insert(ClientStatCache[player], PlayerData[player]["Stats"])

Client script:

local ClientStatCache = require(game.ReplicatedStorage.ClientStatCache)
--Quests:Create(require(qqFolder["Bob's Adventure"]))

local Stats
repeat
    wait()
until ClientStatCache[player] and ClientStatCache[player] ~= nil and ClientStatCache[player]
Stats = ClientStatCache[player][1]
print("Day Completed")
