Hmm, I don't know enough to give you a confident answer yet. The information extracts provided do not contain specific details about the issue you're facing with the Airbyte's latest version not cleaning up the completed pods properly using Helm chart. However, it's important to ensure that your Helm chart and Airbyte version are compatible and up-to-date. You can check the [official Airbyte documentation](
https://docs.airbyte.com/deploying-airbyte/on-kubernetes-via-helm) for more details on deploying Airbyte on Kubernetes using Helm. If the issue persists, I recommend reaching out to the Airbyte community on their [discussion forum](
https://discuss.airbyte.io) for more specific assistance.
