Filebeat has been updated from 8.11.1 to 8.13.1, but the Filebeat agent in Kibana is still 8.11.1

ELK is installed on RHEL 8.8, and Filebeat is installed on Kubernetes.

Currently, all versions have been updated from 8.11.1 to 8.13.1. Below is the complete information about the current environment:

  • Elasticsearch version: 8.13.1
  • Logstash version: 8.13.1
  • Kibana version: 8.13.1
  • Filebeat version: 8.13.1

However, after updating Filebeat to 8.13.1, the version of the Filebeat agent displayed on the Kibana website is still 8.11.1. Additionally, the pod name is still the old 8.11.1, and this pod can no longer be found on Kubernetes. The currently running Filebeat on Kubernetes has also been confirmed to have been updated to version 8.13.1.

I am wondering if this is a bug?
