jump animation stays while pressing arrow keys until I release the arrow keys

So I've been playing with these for the passed few days and I just can not figure it out. When I jump and use the left or right arrow keys and hold it as I land on ground the jump animation stays on and it moves back and forth in the jump animation until I release the arrow keys and the run animation or idle takes effect.
