Hide segments during segmentation


I am working on T1 weighted images of lower leg muscles and I am manually doing the segmentation where each muscle I am interested in corresponds to a segment.

I opened the saved file .mrml but when I want to hide a segment by closing the little eye, it does not disappear. Moreover, it is not possible to delete errors in the drawing in order to improve the precision of the segmentation. 1 2 I tried to restart 3DSlicer but nothing happens.

I attached two screenshots so the problem may be better understandable.
How can I fix this problem?

Thanks for your help,


Probably you have multiple segmentations. You can see all the segments in all segmentations at the same time if you go to Data module.
