Share Extensions (Mail, Messages, and Flickr) Not Showing

The ShareKit extensions for Mail, Messages and Flickr are not showing in the Share Menu, or the Extensions System Preference. Everything else is fine. I do have a Flicker account set up in Internet accounts. I’ve repaired permissions, and tested it in other accounts on my Mac - same thing. Can’t share to Mail, Messages or Flickr. I’ve even tried the terminal command from https://support.apple.com/en-us/HT203129. Shows them loading, but not showing in the System Preferences or the Share menu. Yes, I even closed both System Preferences and Safari.

Any suggestions? I really would like to resolve this.

Thanks.

Dave
