Error While Adding Tool

I am working on “Segmentation” page

I was trying to add PlanarFreeHandContourSegmentationTool.
However, after adding it, when I use that tool I get “A contour segmentation must be active” error

This doesn’t happen if I add other features like “PlanarFreeHandROI” or “LivewireContour”

We currently don’t support contour creation. You’ll need to create a contour-type segmentation first, then add it using the tool.
