I imported pictures and they are not showing in the library. The list stops at 2019/03 (see screenshot) and I can't access the pictures on that pannel. They are showing in the lower bar and in develop mode.
Of course, I can't organise they as they don't show in the navigator bar.
Your screenshots show you are on Windows running Lightroom Classic, so this is the correct forum. ("Lightroom" is the official name of the cloud-based similar product. Thank overpaid marketers for the confusion.)
