Activating rehearsed timing

[plusJMC]

Hello, I am following the instructions of the Getting Started With LibreOffice 4.2 guide and on page 189 it says:

To apply a different display time to each slide in your presentation:

To apply a different display time to
each slide in your presentation:

1. Go to Slide Show > Rehearse Timings
   on the Menu bar and the slide show
   starts.

2. When you are ready to advance to
   the next slide, mouse click on the
   display background or press the right
   arrow or spacebar on your keyboard.

3. Impress will memorize the timings
   for each slide and advance to next the
   slide automatically using the timings
   when you run the slide show.

I follow these instructions but when play the presentation again it does not follow the pattern of times selected during Rehearse Timing. It follows what I have selected in the Slide Transition of the side bar.

That happened to me on:
LO 4.2.7.2 on Ubuntu 14.04
and
LO 4.4.3.2 on Windows XP

Please, is there anything else I have to do or configure?
