Shifting problem in model slice display

Hi,

I created a segment and exported it into a model. When I turn on slice display visibility, I notice an extreme contour shift, as shown in the images below.


Why is this happening?

The labelmap consists of 3D boxes, and compared to that the surface is a continuous representation. I think simply the slice position you look at is not at the center of the labelmap voxel. Btw I wouldn’t call a half voxel discrepancy extreme. It’s similar to the partial volume effect.
