Don't know if it is a bug but I noticed that when I delete a user his entry in table "users" is deleted but the entry in table "user_profile" remains. Why?

I am having issues removing users too from XOOPS 2.2RC. I remove the user from any group as directed in another post then delete the user. From the admin side everything looks ok and appears as though the user has been removed though the users email and username are still stored in the database. After deleting the user they can still login but cant see anything because they no longer belong to a group. Because of this when a user is deleted their email and username are still in the database they cant be recycled and used again. Do I have to manually remove the info from Mysql?

2.2.1 has now been released.

Simply brilliant observation... but it still doesnt work.
