A funny issue with strokes

Hello Community,

I am new here and getting my grasp around Lottie and AE. :slight_smile:
In my Lottie Preview: https://lottiefiles.com/share/1e45u0cy there is a funny jump of the leaves between frame 21-24.
I thought that maybe the thickness of the stroke but even when I increase it, the jump is still visible: https://lottiefiles.com/share/5t7vqkh3

Anyone has ever encountered anything like this? Any idea or suggestion?
Thank you for your help!
