How to create custom fields profile synchronized with phpBBforum?

Hi,

I installed phpbbforum and it is great I could say. But I have one problem :/

I tested default profile fields if they can be synchronized between Drupal and phpBBForum and yes default ones are but I created also additional fields in Profle module (same fields created in Forum) and I expected to see this NEW fields in phpbbforum module settings under custom profile field mapping but my new fields have never been there :/ and never synchronized :/.

Does anyone know what must be done in order to see that new fields in settings and later be able to synchronize them?

Thank you in advance for help.
