Duplicate Alerting issue.

I have a bit of a problem with my alert config.

Suppose I have two macros defined for host groups

$databases=%(sdb.*) $unix=%(sdb.*|www.*)

Then I create some records like...

HOST=$databases MAIL managers at foo.com MAIL dba at foo.com

HOST=$unix MAIL managers at foo.com MAIL unix at foo.com

The problem is then, that the managers group will get two alerts when there is a problem with an sdb* box.

This was not the behavior under BB. Is there a way to keep the duplicate alerts out?
