How to TweenPart From One side Only and Other Stuff?

Long Story Short: I'm learning to script but i know a little bit of scripting. So I make small codes for Practice. I Made a Mud-Wall Magic Code But with A CoolDown Indicator. The Mud-Wall Increases in size by Tweening but it is tweening on all sides. The Indicator Changes color when CoolDown has not finished but it only seems to change once and not go back to the original color. A Videos For Help

Important Code:

local tweenInformation = TweenInfo.new(
1,
Enum.EasingStyle.Linear,
Enum.EasingDirection.In,
0,
false,
0
)
local partInfo = {
    Size = Vector3.new(8.623, 5.755, 2.023);

}

And

cooldownindicator.BackgroundColor3 = Color3.new(194, 194, 194)
cooldownindicator.BorderColor3 = Color3.new(250, 250, 250)
Cooldown = true
wait(10)
cooldownindicator.BackgroundColor3 = Color3.new(125, 125, 125)
cooldownindicator.BorderColor3 = Color3.new(71, 71, 71)
Cooldown = false
