hide1cloze cards have everything hidden.

I've started creating the attached file for learning swedish (from german).

However, in all hide1cloze cards both options are hidden when running org-drill.

I am using org-drill from the contrib directory in org 8.3.6.

The file spanish.org from this example works fine. I don't see a difference in the hide1cloze cards, so why is it not working for my file.

I figured it needs to be between :PROPERTIES: and :END: - maybe this is something that the parser could handle automatically the first time it parses the drill items.

as per my last comment, I'm marking this not as a bug, but as an enhancement.
