Billboard Gui is opposite side?

My text label for my GUI is a damage indicator. I made a damage indicator everything is working fine but the numbers are like 02 instead of 20. Can someone help me fix it.

My code:

local function TweenOut(Obj,properties)
	local TS = game:GetService("TweenService")
	local TI = TweenInfo.new(1,Enum.EasingStyle.Linear,Enum.EasingDirection.Out)
	local Tween = TS:Create(Obj,TI,properties)
	Tween:Play()
end
