[CP2K-user] Error in print &molecular_dipoles under &LOCALIZE in cp2k

Hi all,

May I ask how to print the dipole moment per molecule of the system in 
cp2k? I tried to do print molecular_dipoles in LOCALIZE:

   &LOCALIZE

      METHOD CRAZY

      USE_HISTORY

      &PRINT

        &MOLECULAR_DIPOLES

          FILENAME

          COMMON_ITERATION_LEVELS 1

        &END MOLECULAR_DIPOLES

      &END PRINT

    &END LOCALIZE


I got the output with dipole for each atom instead of each molecule. And 
the charge and dipole in that file look strange. Here is the output:

   # molecule nr,      charge,           dipole vector,           
dipole[Debye]

This is just for a neutral water molecule cluster in a big box. The charge 
and dipole for each atom looks large and strange. 

Does anyone know what might be wrong with this?
