The 3d model disappeared and the thresholds are gone.

Can someome help me restore it bake to normal,

It seems that you have loaded the file as a volume instead of a segmentation.

You can either save the file with the .seg.nrrd file extension to give a hint to the application to load it as a segmentation. Or you can keep using the .nrrd file extension but then you need to manually select DescriptionSegmentation in Add data window.
