Technically, it was meant to work like that. The original idea was that the top graph would be the only graph and it would be able to be filtered. Due to the fact that it uses the same Model as the Security Exceptions page that also had the side-effect of filtering the Security Exceptions page. So the filtering was removed from the Control Panel page and the lower graph (exceptions by type was added). But I never removed the filtering feature, even though it's no longer necessary. In retrospect, I should have done that.
I'll change that for the next version of Admin Tools. The way it's working right now is very confusing and there is no longer a use case for it.
