I still have this issue even after everything is updated.
If I draw a text box FIRST, the IC document, whether dragged or placed into that text box, has a high chance of not showing up in the assignments panel.
Draw the text box(es) first, place or drag-and-drop the IC document into the box, then select all text boxes for that story, cut, and paste in place.
Place/drag-and-drop the InCopy document directly on the page.
As confirmed by the user, The issue is resolved with the latest InDesign CC 2018(188.8.131.52).
