Problem with profile fields save system

Hi,

I noticed what It seems to be a bug with Drupal 6 and the profile system.

I have an action that save some profile hidden field depending on others visible field that the user fill when it edit his account.

Look especially to the end of code of my action :

  drupal_set_message('<pre>'.print_r($fields, true).'</pre>');
  drupal_set_message('<pre>'.print_r(user_save($updated_user, $fields), true).'</pre>');

And look now the output when the action is triggered :

Output of $fields

#

Array
(
    [profile_api_status] => Error
    [profile_charname1] => 
    [profile_charid1] => 
    [profile_corpname1] => 
    [profile_corpid1] => 
    [profile_gender1] => 
    [profile_race1] => 
    [profile_bloodline1] => 
    [profile_balance1] => 
    [profile_charname2] => 
    [profile_charid2] => 
    [profile_corpname2] => 
    [profile_corpid2] => 
    [profile_gender2] => 
    [profile_race2] => 
    [profile_bloodline2] => 
    [profile_balance2] => 
    [profile_charname3] => 
    [profile_charid3] => 
    [profile_corpname3] => 
    [profile_corpid3] => 
    [profile_gender3] => 
    [profile_race3] => 
    [profile_bloodline3] => 
    [profile_balance3] => 
)

Output of user_save() (values with XXX are correct but hidden for confidentiality)

#

    [profile_api_status] => Error
    [roles] => Array
        (
            [2] => authenticated user
        )

    [profile_uid] => xxx
    [profile_api] => xxx
    [profile_charname1] => xxx
    [profile_charid1] => xxx
    [profile_corpname1] => xxx
    [profile_corpid1] => xxx
    [profile_gender1] => xxx
    [profile_race1] => xxx
    [profile_bloodline1] => xxx
    [profile_balance1] => xxx
    [profile_base-attributes1] => xxx
    [profile_attributes-enhancers1] => xxx
    [profile_total-attributes1] => xxx
    [profile_skills1] => xxx
)

You can see that only profile fields with "1" terminaison are filled, whereas my $fields table contain the 1, 2, and 3...

See the attached screenshot to see that my profile fields are correctly set up in administration.

It's a very strange bug and I have absolutely no ideas of what can cause this strange behavior, I really need help.

Thank you
