My segmentations disappear when trying to change the resolution

Hi, I’m trying to change the resolution of a segmentation to then use a grow filter to adapt it to the vessel structures of my CTs. My problem is that, when setting any oversampling factor, my segmentation seemingly disappears. Why is that and how could I solve it?
Thanks in advance.

how do you set an oversampling factor?


from this window, which gets opened through this icon

What if drag the segmentation in Data module to the Slice view windows?
