Compatibility with confluent kafka

[stefannmih]

I have an old kafka cluster installed with confluent-5.5.0
I have kafka-manager-1.3.3.22

I am experiencing this issue:

[WARN] - from kafka.manager.actor.cluster.KafkaManagedOffsetCache in KafkaManagedOffsetCache
Failed to process a message from offset topic on cluster X

From what I've found, the kafka manager might not be able to understand some metadata from the kafka topics and this is why it's throwing this warning.

I've read this thread 744 that says this is probably caused by log.message.format.version incompatibility between Kafka cluster & CMAK.

1. I would like to know if there is any compatibility matrix between the kafka manager and the confluent version that I use.
2. Is there a specific version for log.message.format.version that I should use? Right now I use the default one.
