Why the Acceleration of Simulated Proxy is delay? How to make it change immediately?

When I monitoring the acceleration of the simulated proxy in the animation blueprint, I find that it slowly drops to 0 after I release the move button, but in the authoritative’s and autonomous proxy’s animation blueprints, the acceleration drops to 0 immediately when I release the move button. which makes it difficault to switch the state correctly on the simulated proxy. Is there any way to keep the acceleration of the simulated proxy consistent with that of the server? (Since my animation blueprint uses thread-safe functions, properties can only be read through property access nodes.) I tried to modify almost everything about the character movement component’s properties, but to no avail.
