any idea why this happens?

extends KinematicBody2D

const ACCELERATION = 500
const MAX_SPEED = 100
const FRICTION = 500

var velocity = Vector2.ZERO

onready var animationPlayer = $AnimationPlayer
onready var animationTree = $AnimationTree
onready var animationState = animationTree.get("parameters/playback")

func _physics_process(delta):
	var input_vector = Vector2.ZERO
	input_vector.x = Input.get_action_strength("ui_right") - Input.get_action_strength("ui_left")
	input_vector.y = Input.get_action_strength("ui_down") - Input.get_action_strength("ui_up")
	input_vector = input_vector.normalized()
	
	if input_vector != Vector2.ZERO:
		animationTree.set("parameters/idle/blend_position", input_vector)
		animationTree.set("parameters/walk/blend_position", input_vector)
		animationState.travel("walk")
		velocity = velocity.move_toward(input_vector * MAX_SPEED, ACCELERATION * delta)
	else:
		animationState.travel("idle")
		velocity = velocity.move_toward(Vector2.ZERO, FRICTION * delta)
	
	velocity = move_and_slide(velocity)

    It's hard to tell so you might need to spell out what the 'this' that happens is.

    dummyyxD you are using an animation tree, right?
    Make sure all of the states have that setting with the line set to the dotted line.
    It's a dropdown option, and if it isn't on the dotted line it sometimes causes problems for movement systems like this
