Dear JaumeDEscriu,
Thank you for the info on the composers' names. Only admins can change a composer category, but I will mention your recommendations to the admin who is most up-to-date with the most common form of the name used by libraries and indices worldwide. If the name appears in the original Catalan or Valencian in the "Alternate names" listing, then the present form of the name is that most often encountered in indices, etc. The composer's page should come up if you search using the orginal form of the name.
