nagios sending notifications to wrong contacts

I'm having a small issue that has been bugging me for some time now, and now it's time to fix it :) I have a Nagios Core 3.5 install running. In the Nagios configuration, we have a couple of service templates defined, all of these have a contact defined. We have some services that have to notify a different contact than the default contact defined at the service. According to what I have read here I would expect the service definition to overwrite the default contact. Example config: define service{ name generic-service-5min notifications_enabled 1 contacts contact1 notification_options w,u,c,r notification_interval 60 notification_period businessday register 0 } define service{ use generic-service-5min host_name HOST1 service_description CustomService check_command CustomService contacts Contact2 } Maybe my understanding of this is incorrect and is this how it should work. But hopefully we can find a way that doesn't lead to messages to two different contacts but only one. Thanks for any information and/or insights.
