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?
