Ambari Alerts – How to change Kafka port?

Hi there,
I have an installation of HDP 2.3 with Kafka. I changed the default Kafka port 6667 given by Ambari, to 9092. I use the “listeners” variable to do it, by settings it to PLAINTEXT://localhost:9092. The Kafka service runs fine, but Ambari alert of Kafka service still checks port 6667.
Is this a bug?
How do I change the alert’s port to check to 9092? I don’t see any option to do it in “edit” mode in the ambari alert.

Thanks!
Krzysztof
