Select don't record the value

I have created a blueprint for a select field:

work-type: 
  type: select
  options:
    - Drawing
    - Painting
    - Etching
    - Object
    - Installation

But when I save the value and exit the edition page and return to the page the value is not registered on the page. What did I make wrong?

Thanks, excuse me for the very foolish doubts, but when one is middle of the code, is difficult to see these very important little details.

And thanks for the agility. You are incredible, @texnixe.
