If a folder is deleted in Assets, it remains in place in Google Cloud Storage (any files/images inside the deleted folder are however deleted in Google Cloud too).
If a folder is moved to a new location in Assets, the directory remains in the original location in Google Cloud Storage, but the files inside are moved. The directory that was moved is created in the new location and contains the files/images that were moved (as expected). So you end up with two folders, the original (empty) and the copy in the new location (with files inside).
Re-indexing brings back these 'ghost' folders.
