moving platforms stop when synced to physics

Hello, i am creating a 2D platformer and i’ve just setup moving platforms using a KinematicBody2D, paths and an animation player, following this tutorial: Moving Platforms in Godot Engine - Zero Lines of Code

The problem is that the platforms simply don’t move when i sync their KinematicBody2D to physics as asked in 3:17, and if i turn that off, they move, but get all jittery and glitchy.

How do i fix this?
