Amaya generating repeated ids in Table of contents

Hi,

I found Amaya (amaya_wx-10.0-pre2_i386.deb) generating repeated
ids in Table of contents. In the attached file
sections:

  1. Magnitudes, unidades y sistemas de medida
and
  2. Magnitudes usuales: variables de proceso 

get the same link: #Magnitudes

I don't know if this is a version specific problem.
