Vanishing notes after clicking on "Search & Outline"

In the past, when I was annotating documents in MN and clicked on “Search & Outline,” the notes would transform from cards to notes in the left column. However, whenever I click on “Search & Outline,” I get a blank left column and no notes.

What’s happening and how can I fix this?
