Since episode 2x38, the show started to release 2 episodes each day, but the end credits or the first episode were always cut. They were only shown as a separate clip in the Official Facebook page of the show.
All the episodes were titled but only the crew members knew it. During the broadcast of the series on television, the titles of each episode have never been shown, not even on the official website of Televisión Española, where everyone can watch them for free. Only the broadcast dates are shown as titles.
