the generatet file has no annotations... on Onyx Boox Note Air2 Plus

Hi,
have test this Plugin with my Onyx Boox Air2 Plus.
The exported *.txt file from my boox contains some informations about the book and the author and all my annotations too.
After change the filetype to *.md and select "Extract Onyx File" from contex menu, i get only a file with title and authors - thats all!
No annotations etc.
I´ve add the exportet file and renamed file to this issue. Maybe it helps you.

Greetings from Hannover ;-)
