At this stage, I want to remove small clusters within the Segment\_2. I set the editable area Inside Segment\_2 (red), set the small cluster size 100 voxels. When I run this, everything Segment\_2 is essentially cleared. After the filter is ran, there are no voxels assigned to it.

Is this a bug or am I missing something?
