BUG: Cloner does not clone many settings

I tried to clone a multisite blog and I noticed the following settings did not get cloned:

- General: default Email
- Reading: Multisite privacy option to ask for a password (active with MPMUDEV Plugin)

WMPL Plugin: I had to completely reconfigure the language settings.

Kriesi Enfold Theme Settings: I had to completely reconfigure all theme settings.

Appointments+ Plugin: Some settings did not get cloned

I manually edited all configurations, and I still need to check if other plugins's settings have been cloned correctly.

Please advise if these are bugs or I'm doing something wrong.
