Character Objects Physics does not update till frames later...

Hi, I'm currently working on a capstone project and am trying to finalize a generic humanoids movement and physics. All of the physics are run on a kinematic environment, with every single object being kinematic as well. I have hardcoded all of my characters physics into the scripts, including jumping, walking, running, etc. The physics themselves are functioning as they should, my problem is when an action is called, the physics don't update until frames later. As demonstrated in the gif I posted, whenever I input a jump for my character, the animation starts on frame 1, but the physics don't kick in until a little after the animation begins. The same can be seen when my character collides with the ground, when the two collide, the landing animation does occur but once again, the physics don't kick in until a little after, giving the illusion that I've fallen through the ground before the game corrects the characters position. Any fixes or tips would be most appreciated!
