Duplication Issue: Flume Kafka Data Transfer from Local to Cloud Kafka

I employ Flume Kafka and a Flume channel to transfer data from a local Kafka instance to a remote Kafka setup. Occasionally, I've observed instances where Flume duplicates messages upon reaching the cloud-based Kafka destination.

Here's how my configuration looks like
# Define sources, channels, and sinks
agent.sources = kafka-source
agent.channels = kafka-channel

agent.sources.kafka-source.type = org.apache.flume.source.kafka.KafkaSource
agent.sources.kafka-source.channels = kafka-channel
agent.sources.kafka-source.setTopicHeader = false
agent.sources.kafka-source.kafka.topics = test
agent.sources.kafka-source.kafka.bootstrap.servers = localhost:9092
agent.sources.kafka-source.kafka.consumer.group.id = test-group
agent.sources.kafka-source.kafka.consumer.auto.offset.reset = earliest
agent.sources.kafka-source.kafka.consumer.enable.auto.commit= true

agent.sources.kafka-source.interceptors = doSomethingInterceptor
agent.sources.kafka-source.interceptors.doSomethingInterceptor.type = com.sample.DoSomething$Builder

agent.channels.kafka-channel.type = org.apache.flume.channel.kafka.KafkaChannel
agent.channels.kafka-channel.parseAsFlumeEvent = false
agent.channels.kafka-channel.kafka.topic = cloud_test
agent.channels.kafka-channel.kafka.bootstrap.servers = cloud_kafka_bootstrap_server:9092
agent.channels.kafka-channel.kafka.consumer.group.id = cloud_test_group
agent.channels.kafka-channel.kafka.producer.acks = 1
agent.channels.kafka-channel.kafka.producer.batch.size = 65536
agent.channels.kafka-channel.kafka.producer.client.id = cloud_kafka_client_id
agent.channels.kafka-channel.kafka.producer.compression.type = some_compression_type
agent.channels.kafka-channel.kafka.producer.linger.ms = 50
agent.channels.kafka-channel.kafka.producer.max.request.size = 33554432
agent.channels.kafka-channel.kafka.producer.security.protocol = SSL
agent.channels.kafka-channel.kafka.producer.ssl.endpoint.identification.algorithm =
agent.channels.kafka-channel.kafka.producer.ssl.enabled.protocols =
agent.channels.kafka-channel.kafka.producer.ssl.keystore.location =
agent.channels.kafka-channel.kafka.producer.ssl.keystore.password =
agent.channels.kafka-channel.kafka.producer.ssl.keystore.type =
agent.channels.kafka-channel.kafka.producer.ssl.truststore.location =
agent.channels.kafka-channel.kafka.producer.ssl.truststore.password =
agent.channels.kafka-channel.kafka.producer.ssl.truststore.type =

Start with the supplied Flume KafkaSource and KafkaChannel configuration, focusing on the consumer offset and producer settings involved in the local-to-cloud transfer. Reproduce the duplication if possible and determine the conditions under which messages are delivered more than once; done should include a confirmed cause and a documented configuration or behavior change.
