Hi thanks for the question. It is expected in particular during the initial stages of training. As most of the labels are small (except for Labels #0 which are always the gland segmentation), so they would not have any overlap before more iterations in. Even when it closes to convergence, some of them still can be quite small even zeros.
Just FYI: these non-overlap landmarks still generate useful gradients, due to the multiscale loss, as explained in the paper.
