We get <img width="807" height="292" alt="Image" src="https://github.com/user-attachments/assets/94c63a49-6c6d-4405-8fdf-b53c5d7e3fc9" /> instead of the actual time <img width="288" height="145" alt="Image" src="https://github.com/user-attachments/assets/2b789a26-7783-4f24-9bb6-1297d083e2de" /> The fix is to add a unique identifier to the id for each mapped polyline.
