Art not showing in Harmony


I reopened a Harmony file, but am unable to see the art in Camera or Drawing view.

The art is visible in the timeline’s thumbnail view for that layer, and also as a thumbnail in the Library window… just not where it’s needed (in Camera or Drawing view.) I get the same result if I import the tvg file (visible as a thumbnail but not art itself.)

Does anyone know of a solution to this problem?
