I thought the same thing myself but let's not jump the gun. We can neither confirm or deny that Buggy is a shichibukai at this time. I know the evidence seems solid, but we can't say he is until it is confirmed in the manga. Remember, even if the messenger bat does deliver invitation to join the shichibukai, they're just that, invitations. Buggy could just as easily refused.
