I'm cleaning up hard drives space for 2019. Have deleted folders of sessions that I do not need to keep. With sub-solders involved it's faster to delete the parent folders in Explorer then go to LR and Remove the parent folders (and sub-folders) from the Catalog. However, with this update the Remove button is greyed out or when I click it nothing happens. Therefore I can't remove the deleted folders from LR.
