Job check problem

i have a resource that if player job is “ff” show some markers to him
my job is “ff” but i should restart resource when i come to the server for show markers

Load ESX object and PlayerData code :

ESX = nil
local PlayerData = {}

Citizen.CreateThread(function()
	while ESX == nil do
		TriggerEvent('esx:getSharedObject', function(obj) ESX = obj end)
		Citizen.Wait(0)
	end
	while ESX.GetPlayerData() == nil do
		Citizen.Wait(10)
	end
	PlayerData = ESX.GetPlayerData()
end)

RegisterNetEvent('esx:setJob')
AddEventHandler('esx:setJob', function(job)
    PlayerData.job = job
end)

check if player job is ‘ff’ code :

if PlayerData.job ~= nil and PlayerData.job.name == 'police' then
	-- 
end

the code used to interact with markers :

Citizen.CreateThread(function()

 while true do
    Citizen.Wait(0)
    if PlayerData.job ~= nil and PlayerData.job.name == 'ff' then
        local coords = GetEntityCoords(PlayerPedId())
        if GetDistanceBetweenCoords(coords, position.x, position.y, position.z, true) < 20.0 then
   cMarker(27, position, scale, color, false, true)
        end
        if GetDistanceBetweenCoords(coords, position2.x, position2.y, position2.z, true) < 20.0 then
   cMarker(27, position2, scale2, color2, false, true)
        end
        if GetDistanceBetweenCoords(coords, position3.x, position3.y, position3.z, true) < 20.0 then
   cMarker(20, position3, scale3, color3, true, false)
        end
        if GetDistanceBetweenCoords(coords, position4.x, position4.y, position4.z, true) < 20.0 then
   cMarker(36, position4, scale4, color4, true, false)
        end
        if GetDistanceBetweenCoords(coords, position5.x, position5.y, position5.z, true) < 80.0 and IsPedInAnyVehicle(PlayerPedId()) then
   cMarker(1, position5, scale5, color5, false, false)
        end
        if GetDistanceBetweenCoords(coords, position6.x, position6.y, position6.z, true) < 20.0 then
   cMarker(27, position6, scale6, color6, false, true)
        end
        if GetDistanceBetweenCoords(coords, position7.x, position7.y, position7.z, true) < 20.0 then
   cMarker(27, position7, scale7, color7, false, true)
        end
    end
 end
end)

cMarker function :

function cMarker(type, position, scale, color, facecamera, rotate)
    if facecamera == nil then facecamera = false end
    if rotate == nil then rotate = false end
    coord = vector3(position.x, position.y, position.z)
DrawMarker(
	type, 
	coord,
    0.0,
    0.0,
    0.0,
	0.0, 
	0.0, 
	0.0, 
	scale.a, 
	scale.b, 
	scale.c, 
	color.r, 
	color.g, 
	color.b, 
	150, 
	false, 
    facecamera,
    2,
	rotate
)
end

positions :

local position, position2, position3, position4, position5, position6, position7 = vector3(190.94, -903.50, 30.81), vector3(177.20, -905.40, 30.81), vector3(181.14, -905.04, 31.10), vector3(174.0, -913.0, 30.40), vector3(162.61, -881.0, 29.40), vector3(179.40, -908.25, 30.81), vector3(187.74, -904.50, 30.81)
