Strange text bug

Hey, I might just be doing something incorrectly, but when I make a text box and then animate it by making 3 keyframes or more, the text goes backward for some reason. I feel as if I might be animating the text wrong, but no matter how I try to animate it doesn't work. I am trying to make a text box that comes in, moves slowly to the right, then speeds out at the end. Please help I'm a primere pro noob!!!
