Buggy function doesn't return to size if you play with it. Help me please?

This script is buggy, and when I put my mouse off of it, it glitches sometimes and doesnt tween it back to 0, where the x value is originally as the frame. I'd like to know if there's another function of some sort that sets it back to its original position.

JediFrame = script.Parent.Parent.Parent
DescFrame = JediFrame.Desc

script.Parent.MouseEnter:connect(function()
	script.Parent:TweenSizeAndPosition(UDim2.new( 0, 253, 0, 30), UDim2.new( 0, 0, 0, 30), "Out", "Elastic", 0.3)
	DescFrame:TweenSizeAndPosition(UDim2.new( 0, 150, 0, 280), UDim2.new(  0, -150, 0, 20), "Out", "Elastic", 0.5)
end)

Here's the glitch

script.Parent.MouseLeave:connect(function()
	script.Parent:TweenSizeAndPosition(UDim2.new( 0, 0, 0, 30), UDim2.new( 0, 0, 0, 30), "Out", "Elastic", 0.3)
	DescFrame:TweenSizeAndPosition(UDim2.new( 0, 150, 0, 277), UDim2.new(  0, -150, 0, 20), "Out", "Elastic", 0.5)
end)
