Task 2 divergence over 2017's ground truth

We noticed there are divergences between annotations from the ISIC2017-part2 and the ISIC2018-part2 training dataset. There are some inconsistencies on the label “attribute_streaks.” To point out some examples, on images ISIC_0000000, ISIC_0000036 and ISIC_0000037, which belong to both sets, the streaks annotation appear only at the 2017 version. On image ISIC_0000031, the annotation between both datasets also diverge.
Could you please check what happened? Thanks in advance.


Could the organizers clarify the divergence, please? Since the task2 ground truth was previously changed, we would like to know if any other issue could have emerged.

Best regards,
