Tweening Level Gui Breaks when filtering enabled?

So, recently i learned how to use FE. I learned Changing the players Data through the server, and creating a part. But i need help with making a GUI that tweens with the players data (Ill go through further explanation if you dont understand what im saying.) How do i fix this?

DATA SCRIPT:

game.Players.PlayerAdded:connect(function(Player)
    --\\Something to hold the data in
    local Data = Instance.new("IntValue",Player)

TWEEN SCRIPT:

while true do
    wait()

    local XP = script.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Data.StrengthEXP.Value

    local math = ( XP / MaxXP )

    script.Parent:TweenSize(UDim2.new(math,0,1,0),"Out","Quad",.25)
