Logstash consumes same messages from Kafka

Elastic Stack Logstash

I have a problem when Logstash consumes data from Kafka - it consumes the same data over and over again.

I have sent several hundred messages to Kafka but Logstash has been consuming them for about 3 hours and the total messages it consumed so far is 300k.

Configuration settings are quite simple:

input {
  kafka {
    bootstrap_servers => "..."
    topics => ["logstash"]
    codec => "json"
  }

What could be a reason of such behavior?

Did anybody have the same problem?
