How to fix a bug that makes a player the only one able to see the particles attached to him?

This has already broke 2 of my wannabe games and i want to fix it. Whichever Particle Emitter is attached to a player using a script is only seen by that certain player and no one else on the server all particle emitters i use are new instances with player parts as their parents.Since every game that i try to make goes around particle emitters quite a lot i need a fix for this.

P.S everything was working perfectly until a few weeks ago.

here's one of the many codes i've been using that result "local particle emitters only seen by a player wearing them"

local jun = game.Players.LocalPlayer
Stuff = false

local function ssj()
if Stuff == false then
Stuff = true

 demm1 = Instance.new("Decal")
demm1.Name = "demm1"
demm1.Texture = game.ReplicatedStorage.Dem1.Texture
demm1.Face = game.ReplicatedStorage.Dem1.Face
demm1.Parent = jun.Character.Head
demm1.Color3 = game.ReplicatedStorage.Dem1.Color3


local dema = Instance.new("ParticleEmitter")
dema.Texture = game.ReplicatedStorage.dema.Texture
dema.Color = game.ReplicatedStorage.dema.Color
dema.Rate = game.ReplicatedStorage.dema.Rate
dema.SpreadAngle = game.ReplicatedStorage.dema.SpreadAngle
dema.Speed = game.ReplicatedStorage.dema.Speed
dema.Size = game.ReplicatedStorage.dema.Size
dema.Parent = jun.Character:FindFirstChild("UpperTorso")
wait(2)
dema:Destroy()

aura = Instance.new("ParticleEmitter")
aura.Name = "aura"
aura.Parent = jun.Character.RightFoot
aura.Size = game.ReplicatedStorage.dem1a.Size
aura.Texture = game.ReplicatedStorage.dem1a.Texture
aura.LightEmission = game.ReplicatedStorage.dem1a.LightEmission
aura.Speed = game.ReplicatedStorage.dem1a.Speed
aura.SpreadAngle = game.ReplicatedStorage.dem1a.SpreadAngle
aura.Rate = game.ReplicatedStorage.dem1a.Rate
aura.Color = game.ReplicatedStorage.dem1a.Color
aura.Lifetime = game.ReplicatedStorage.dem1a.Lifetime
aura.LockedToPart = true

aura2 = Instance.new("ParticleEmitter")
aura2.Name = "aura2"
aura2.Parent = jun.Character.LeftFoot
aura2.Size = game.ReplicatedStorage.dem1a.Size
aura2.Texture = game.ReplicatedStorage.dem1a.Texture
aura2.LightEmission = game.ReplicatedStorage.dem1a.LightEmission
aura2.Speed = game.ReplicatedStorage.dem1a.Speed
aura2.SpreadAngle = game.ReplicatedStorage.dem1a.SpreadAngle
aura2.Rate = game.ReplicatedStorage.dem1a.Rate
aura2.Color = game.ReplicatedStorage.dem1a.Color
aura2.Lifetime = game.ReplicatedStorage.dem1a.Lifetime
aura2.LockedToPart = true


end
end

local function nossj()
	if Stuff == true then
		Stuff = false
	
demm1:Destroy()
aura:Destroy()
aura2:Destroy()
end


end

jun.Chatted:connect(function(Msg)
local msg = Msg:lower()
if string.sub(msg, 1, 7) == "demon1" then
wait(0.1)
ssj()
end
if string.sub(msg, 1, 13) == "dem1" then
wait(0.1)
ssj()
end
if string.sub(msg, 1, 6) == "/e dem1" then
wait(0.1)
ssj()
end
if string.sub(msg, 1, 10) == "/e off" then
wait(0.1)
nossj()
end
if string.sub(msg, 1, 3) == "off" then
wait(0.1)
nossj()
end
end)
