Load the labelmap, convert to segmentation in Data module (right-click the labelmap volume and choose to convert to segmentation), and use Segment Editor to fix the segmentation. When you finished your corrections, you may convert the segmentation to labelmap volume using Data module (right-click on segmentation node and choose to export to labelmap).
