When I am trying to delete images from the Library, I click on the black flag and all the images disappear. I can choose them again from the list of dates on the left but this keeps happening. I also do not see the option to use the Loupe or Grid views. The flags do not appear on the images I try to select when I get them back into view. The only image that seemed to work was one in a subfolder but most of my images are in the main folder that are categorized by date. What gives with this?
