NNInteractive fails to export segmentations

I am working with NNInteractive module in 3D slicer on 3D NRRD files (I converted from DICOM via 3D slicer itself). The module worked smoothly and nicely generated volume segmentations, but once I tried to export them through the ‘segmentations’ module, and the reference volume is assigned to the correct original image, I got the following error:
[Qt] libpng warning: iCCP: known incorrect sRGB profile
[Qt] libpng warning: iCCP: too many profiles
[Qt] virtual double qSlicerSubjectHierarchyFolderPlugin::canOwnSubjectHierarchyItem(vtkIdType) const : Input item is invalid
[VTK] Warning: In vtkMRMLSubjectHierarchyNode.cxx, line 2156
[VTK] vtkMRMLSubjectHierarchyNode (0x4ef0eb0): GetItemDataNode: Invalid item ID given

I would appreciate your help with this matter.

The subject hierarchy is probably getting confused. You should be able to save using the regular Save dialog.

What do you mean by save using the regular Save dialog?

I mean File->Save Data

I will try!

Thanks,
