How to add jump animation to my character?

Hello again, I have made my third person character in a blank project completely from scratch, and after experimenting with what you recommended with the jump triggered when button is pressed, i feel like I want the animation to play when the player is falling so I left it as default. There are two small problems though. This is what my state machine looks like


and the jump is doing its function but when the state changes from jump idle to jump down there is a massive lag like this


What do you think is the problem?
