IWR6843AOP: Tracking splitiing from One person tracking

Part Number: IWR6843AOP

Hi, 

When running the 3D people counting demo, 'track splitting' occurs when the upper and lower parts of an object are mistakenly treated as separate tracks. As shown below, It is one person, but has two tarcks. How can I fix it by adjusting configuration. I would like to know how to avoid track splitting and improve the accuracy of the radar target tracking. Thanks in advance. Kyle

This is configuration I used.
