Issue with Lidar data and 3d annotation not matching

[yhk1515]

Hello, I opened the 00000.pkl file in the Lidar folder and the 00000.pkl file in the 3d_annotation folder at the same time and visualized it as a point cloud, and the 3d bounding box doesn't exactly match the object that exists in Lidar. Please help me out how to match this. Thank you.
