Problems with directories of the roles

Good I have a problem with this module:
In my drupal installation I have created eight roles, and so far each role created
WEBFM allow me to assign the default folder, but with the roles that I created last has not left me, I have four roles is that if I appear in the configuration of WEBFM but the rest do not appear to me, I've also made the test delete a role and recreate it with the same name and that role than before if they appeared and had assigned its board no longer appears. It may be because there is a limit of roles to assign folders? or is it a failure of soda? I also tried to run cron and has not taken effect.

Thanks in advance and greetings.
