Keyframing not working, what am I doing wrong?

Hello there! I’m having a hassle with keyframing refusing to animate for some reason I don’t know. I’m
animating a person walking towards a soccer ball and he’s supposed to kick it, but I can’t make him do any animation after the two that I’ve already made (moving forward + walking animation). I’m currently trying to make a “kickin” animation , but when I enter a keyframe of it, it sort of takes over the whole animation, like he will walk towards the ball with a leg back up in the air, or it does nothing at all. As you can see the action I’m trying to animate is called “Kick”. Thanks for any help :slight_smile:
