I have quite a few resources that don't show the title in the library info pane or in the resource info panel. I don't know whether this bug would manifest on the same resources or on other random resources (I can't find a pattern as to which get affected). The easiest way to check is to open the library info pane, then select a resource and use the down arrow to quickly cycle through resources while watching for missing titles in the info pane.
Most of the affected ones look like this, but occasionally one will have a short title in the full title field and vice versa.
