Context not imported from kinkless
 

Importing my kinkless document, I noticed that contexts are not imported, so every item in the imported lists is contexless.

Importing worked proporly sometimes ago, when I started to evaluate Omnifocus (when the menu item was "kinkless importing"). I tried with several different kinkless files and every time I had the same behaviour.

Any idea?

I can answer to this by myself. If a contest is unassigned (blank) in kinkless, all context aren't imported.
Modifying the unassigned context into an existing one, the import works fine.
