Unity Perception: Semantic Segmentation not capturing whole object

[Sultanalshafian]

Hello, I am facing issue while running the semantic segmentation for an HDRP project. I am not able to capture the whole object in my scene. I have attached two images, if you see, the front portion of the vehicle(the roller) is not properly captured and missing in the segmentation. Anyone have idea which settings should i change to capture the whole object?
