Issue of Metahuman 's hair scale by animation, and How to fix it?

This model was downloaded from MetaHuman with the Low (Optimized) settings and imported into UE5.5. After configuring everything, I noticed an issue with the Hair object. When playing character animations, the hair model appears to scale along the X-axis during the animation. I have recorded a video to demonstrate the issue. Could you please advise on how to resolve this? Thank you!
