The player's jump goes constantly, it does not stop, what should I do?

Question

Unity

Made animation in unity, player has idle, jump, walk. The player during the animation, in game-, can stand still, walk left and right, but as soon as I press the space bar, the player jumps, but does not stop in place. He does not jump properly if I want to jump onto a platform. And if I want to walk, he starts walking to the left to the right in a jump pose, it shouldn't be like that. How to fix it? It looks like the animation is done right.
