I have the same issue and don’t see the “WP Knowledgebase” option when importing. Can you tell me what I am missing?
Below are screen shots of the import process:

I am not given any other options, the plugin is installed and activated.
FYI – tried it on another website with same results.
HELP! 🙂
Thanks!
