about point prompt

[yyy1998-i]

Hello author, I used the point prompt to verify after the completion of training, why all images in one center will point many points, while the other center only has one point (I think this is correct), I have checked the image and ground truth, the two centers are the same data type, and the dice of many points is almost zero. The dice of only one point is normal, I am very confused, could you give me some guidance? Perhaps I should continue to check the data and look forward to your reply I think this is correct too many points，dice=0，can't predict the outcome

Sorry，The reason for the multipoint is that the label is not normalized
