Maybe there is something wrong with the master volume. Try to seg labelmap geometry using an “Annotation ROI” as explained [here](https://discourse.slicer.org/t/extend-roi-after-cropping-and-segmenting/6594/3). If you still have issues the best would be if you could share the RTSTRUCT so that we can investigate.
