Why is this script skipping a line that requires it to decrease a size of a gui?

So when i made a tween for a bar to simply increase the size of X, i also added a line so when it reaches the end, it should go back to 0 size, but it doesn't

Here is the script:

local Event = game:GetService("ReplicatedStorage").ClientEvents:WaitForChild("AtomStartProgress")
local Tween_Service = game:GetService("TweenService")

local Fill_Time = 1

local Tween_Information = TweenInfo.new(Fill_Time,Enum.EasingStyle.Linear,Enum.EasingDirection.InOut,0,false,0)

local Tween_Targerts = {

	Size = UDim2.new(0,250, 0,35),
    Position = UDim2.new(0.321, 0, 0.22, 0)
}

local Fill_Tween = Tween_Service:Create(script.Parent,Tween_Information,Tween_Targerts)

wait(0.4)

Event.Event:Connect(function()
	
	Fill_Tween:Play()
	
	wait()
	
	script.Parent.Size = UDim2.new(0,1, 0,35)
	
end)
