Changes to CR not reflecting

Hey team,
Any changes made to the kafka.yaml do not seem to go through, seeing the operator logs:

Could this be the reason? If yes, what would be the steps to resolve this, please?

This is caused by how the watches work in the Kubernetes API server. The watch is simply re-opened after this and should continue to work without any problems.
