There are some errors in the label

[Breeze-Zero]

Hello, we found some problems in the label of brain data, as shown in the picture below (the source of the picture is the 7th slice of file_brain_AXFLAIR_200_6002493 and the 8th slice of file_brain_AXT1POST_201_6002812 respectively), may I ask if it is a labeling error?And how are the criteria for annotation defined？
