If my user is already a subscriber in a list, if he submit again with more fields he get a notice message like : ‘You already subscribe to that list’. And the data is not updated.

I think this is not updated because of this code in sib-api-manager.php line 432:

if ( 'already_exist' == $response['code'] ) {
    return 'already_exist';
}

So you never go to the create_update_user() part.

Cheers
