I've noticed recently that files saved in my encrypted folder no longer automatically encrypt. Some of those do not display the right-click option to encrypt. Even when the folder is marked 'fully encrypted' in the root iCloud Drive Boxcrypter folder. I drag the main subfolder to Finder Sidebar and some show the bc (encrypted) suffix and a few more recent ones do not. I'm using Mac OS 10.13.6 (High Sierra). Suggestions to fix this would be most appreciated.
