[syslog-ng] Odd problem after upgrading from 2.1 to 3

[Jerry Bell]

This config worked in syslog-ng 2.1
source NET {udp(port(514)); tcp(port(5140) keep-alive(yes));};

destination A { file("/var/log/A"); };
destination B { file("/var/log/B"); };

filter A { host ("A");};
filter A { host ("A");};

log { source(NET); destination(A); filter(A); };
log { source(NET); destination(B); filter(B); };

worked as expected that is log messages coming from host A went to 
/var/log/A file
and log messages coming from host B went to /var/log/B.
The two hostnames are resolved locally in /etc/hosts

After upgrading to 3.0.x all the messages duplicated in both files so 
that messages coming from A are written in /var/log/A AND /var/log/B and 
vice-versa.  Any idea why it does not work in 3?

Thank you,

Jerry
