Given that none of those items look to have publisher details either it would leave me to believe that the import process had issues finding a correct DB entry. If you select a game and press CTRL+E to enter the edit window in the window that opens in the upper right there should be a link to a database page if linked or a "Search for Metadata" if it didn't. If the button is there you'll want to use it and see if you can find the correct DB entry and select it, then you can grab images for that game.
