In Lightroom Classic CC 7.0.1 on a Mac when I drag a sub folder of a sub folder up to the main parent folder the moved folder registers correctly in Finder but disappears in the LR file directory. Nothing brings it back except closing and restarting LR. For example, in this directory: My Images... Personal... California... Fall_Colors, if I drag "Fall_Colors" to "Personal" it disappears in LR. It shows up correctly in Finder as a sub folder of "Personal" but is gone, gone, gone in LR. Very annoying. This has happened before and feels like a bug.
