Only black slices upon importing nrrd from 3DSlicer

Hello there,

For a project I need to disassamble a nrrd-stack to separate tifs. I tried to accomplish this using Fiji (ImageJ2). Upon the import of said nrrd showing the segmenation-mask of tissue generated with 3DSlicer, I get a stack of all-black slices. The problem persists with other nrrds from the same project.

Importing foolc.nrrd gives a 3-pixel-wide gray-scale stack, which viewed orthogonally depicts a person. So I guess this is a 3DSlicer specific issue.

Thanks in advance for any help!

Problem solved:
Had to switch to different color view over the LUT menu.
