I'm having an issue with my list views, when using the preview pane style. I have views that worked perfectly, however if I modify the view to change the selected display columns, the preview pane no longer shows the title field from which to hover and display the list item. Are there required fields that the preview pane needs to work? I'm not removing the title field from display.
I want to keep the title field, and the columns I have removed from display are all empty (i.e. not used in the list form). I can change the preview panel to show list items by hovering over the blank space where the title field used to be, it's like it's hidden from view. See below:
