The subscription probably has ended, you may need to update your user titles. This is a little problem with VB, and the developers are aware of it. If a paid group has a title, when the subscription has expired, and the person is moved back to their original group, the title is not updated. So it "looks" like they are still in the paid members group, when in fact their not.

Check and make sure this is not the case. After that, update your members ranks and titles.
