Help with Text tracking behavior

Hello fellow users, I'm trying to fiddle around with text sequences and I was wondering if someone could help me out. Simply, I made a txt box in the center of my background and then added the "Test Tracking" behavior to the text box. I works, however everything seems to be moving to the right from the first letter, while thats useful I still want all the letters to move (being that the left word moves to the left and the right word expands to the right.

example: The "T" in test is stationary and i want that part to move to the left http://www.gfycat.com/VillainousFlimsyIvorybackedwoodswallow
