Tween scaling issue


I just finished the main menu to my game, and I decided to add some nice animations to it. Though when I did, I got some undesired behavior:

How can I fix this? The tween seems to become slower as the screen shrinks and faster as it gets larger. I am using scaling since I want this to be compatible with every screen, or is it not needed? The only thing i’m using sale on is the tweens.
