Problem report for 3D Slicer 5.12.4 win-amd64:

Segment editor: Segment visibility button and color button disapear after moving a segment up or down on the list, same if you do it by right click on the segment in Segment editor to move it up or down, or dragging a segment in the Data module.

(If you save the scene as .mrb, close it and re-open it, everything backs to normal)

How to proceed?
