Movie not recognized in library

[OoDeLally]

I've followed the "Quick Start" steps carefully.
Here is my file hierarchy:

D:
  - Czech
    - Pupendo
      - Pupendo.avi
      - Pupendo.str

Now I get the folder inside my library.

Then what? I cannot see the move anywhere? Where do I click?

The only thing I seem able to do is to click on the Delete button.

Did I miss a step? Is there something wrong with my files?

I'm lost.... Please send a helicopter 🚁

(I tried on both Windows and Linux for the same result)
