My animations of my guns are very messy, why?

NOTE: I am sorry if its too long. I tried to make it nice and neat as much as I could.

I have 4 guns. Each one has a reloading animation.

When I reload one of the guns, it would play the animation of my second tool.

If I reload 2 SMG's, both mags will appear when only one has to appear since I reload one gun.

Local Script: Each tool has this same local script.

local shootEvent = script.Parent:WaitForChild("Remotes").Shoot
local reloadEvent = script.Parent:WaitForChild("Remotes").Reload

local plr = game.Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:Wait()
local hum = char:WaitForChild("Humanoid")

local s = require(script.Parent.Module)

local uis = game:GetService("UserInputService")

local anims = script.Parent:WaitForChild("Animations")

local idleanim = hum:LoadAnimation(anims.Idle)

script.Parent.Equipped:Connect(function(mouse)
	idleanim:Play()
	shootFunction = mouse.Button1Down:Connect(function()
		shootEvent:FireServer()
		wait(0.1)
	end)
end)
script.Parent.Unequipped:Connect(function()
	idleanim:Stop()
	shootFunction:Disconnect()
end)

uis.InputBegan:Connect(function(key)
	if key.KeyCode == Enum.KeyCode.R then
		reloadEvent:FireServer()
	end
end)

Server Script: Each tool has a slighly different script. Example:

local shootEvent = script.Parent:WaitForChild("Remotes").Shoot
local reloadEvent = script.Parent:WaitForChild("Remotes").Reload

local anims = script.Parent:WaitForChild("Animations")
local sounds = script.Parent:WaitForChild("SoundsFolder")

canShoot = true

function shoot_gun(plr)
	local char = plr.Character or plr.CharacterAdded:Wait()
	local hum = char:WaitForChild("Humanoid")
	
	local shootanim = hum:LoadAnimation(anims.Shoot)
	
	--Shoot
	if s.ammo > 0 and canShoot == true then
		shootanim:Play()
		
		sounds.Fire:Play()
		
		shootanim:Stop()
	end
end

function reload_gun(plr)
	local char = plr.Character or plr.CharacterAdded:Wait()
	local hum = char:FindFirstChild("Humanoid")
	
	local reloadanim = hum:LoadAnimation(anims.Reload)

		canShoot = false
		reloadanim:Play()
		wait(1.5)
		reloadanim:Stop()
		canShoot = true
end

shootEvent.OnServerEvent:Connect(function(plr)
	shoot_gun(plr)
end)
reloadEvent.OnServerEvent:Connect(function(plr)
	reload_gun(plr)
end)

Videos of the issue:

Gewehr43 and STG44- The animations are getting very messy and you can see both mags fall down when I reload only one of the tools. video

M1 Garand and Thompson- The M1 Garand plays the animation of the Thompson when it shouldnt. Also, the Thompson is alright for some reason and the M1 Garand isnt disturbing it. video

M1 Garand- This is just to show you how the M1 Garand SHOULD work. video
