Mislabeled testing images

[waylon620]

I noticed that 'audiojack__0001_NG_BX_C2_20231023111538.jpg'(the second image) and 'audiojack__0112_NG_BX_C2_20231023130610.jpg'(the third image) have no defect masks. Based on the other normal C2 view images, which look like the first picture below, it seems these might not have the appropriate label.

I’m wondering if these images are mislabeled, or if they are intended to be considered normal images.
