There's no "pixel labels" menu in Image Labeler (R2018a)

I'm using MATLAB R2018a,and I tried to use the Image Labels to make pixel level mask labels to train my semantic segmentation algorithm. Here are instruct of Image Labels in ： "Use ROIs for object detection, pixel labels for semantic segmentation, and scene labels for image classification." But when I open the APP,there's no "pixel labels" menu in Image Labeler,while there's only the ROI Label and Scene Label menu. Can anybody tell me what's wrong? Thanks a lot!
