Why is there such a big difference in x,y between AV and other agents in val data sequence with id 50255, 20229, 20228 and 28817?

When I evaled my pretrained HiVT on DAIR-V2X, I found that minADE is very big(>100) but minFDE and MR is not that bad. I checked the val data and I found that in the sequences I mentioned before the AV's x,y is very different from other agents'. You can find that in the picture I post:

seq_id 50255, in the folder V2X-Seq-TFD/cooperative-vehicle-infrastructure/cooperative-trajectories/val:

seq_id 50255, in the folder V2X-Seq-TFD/cooperative-vehicle-infrastructure/vehicle-trajectories/val:

20229, 20228 and 28817 looks like has the same questions.

I didn't check out the train data.

Thanks.
