I just noticed today that the majority of my folder names are grayed out in the left pane of the Library module, and the total number of photos in each of the grayed out folders is just shown as "..." now. I seem to still have photos in each of the grayed out folders, and can export and edit and all, but I'm wondering what's changed that caused most of the folder names to gray out. The "?" is not present, so I'm assuming the links to the photos on the hard drive are still good. Just a little concerning that a problem may be brewing. Any help is greatly appreciated.
