Hi, I have an issue with the draw feature for one DICOM set. Every time I draw a segmentation, it disappears from the slice I work on and appears on the next slice. How can I fix it? Thanks.

Can you try with latest Slicer Preview Release?  
Also try if the problem is fixed if you slightly reposition slice views using Shift + Mouse Move.

Could you check if the slice view is positioned at the boundary between two slices? Zoom in a slice view, turn off interpolation in slice view controller (so that you can see each pixel edge) and display slice intersections (crosshair toolbar’s drop-down menu) - you will see if slice intersection line goes through the center of pixels or at the boundary.

I too had similar issue. Solution that worked for me was to drag the slice position to either of the extremes.
